Full Text	BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a rim structure of a satellite dish antenna, and more particularly to a structure that ensures a stable piling action by providing a rim disposed around the periphery of the dish body and recessed outward the inside. 2. Description of the Related Art In the past, wireless communications on ground are usually affected by factors such as landforms and constructions, atmospheric layer, curvature of the earth, and electromagnetic field of the space, so that normal radio waves of communications are reflected, refracted and diffracted to give rise to poor communication effect and quality. Thereafter, a communication satellite is introduced to overcome the shortcomings of traditional wireless communications, and an earth station including a dish antenna, a feedhorn, a low noise amplifier (LNA), a down converter, and a satellite is a major electronic means for receiving satellite signals, and thus radio wave signals transmitted by a satellite in a space orbit can be received effectively. A dish antenna is a window for the whole earth station and its appearance looks like a dish, but its structure is actually in a parabolic shape for facilitating the focus of weak signals dispersed on the surface of the antenna, so that the front side of the antenna becomes a single focal point. Such focal point is usually used as a position for installing a feedhorn, and thus the quality and structural technology of an antenna is significant to the effect of receiving signals. Satellite antennas are used for capturing signals from a satellite in the space and reflecting the signals to a unique focus, but the capability of capturing signals mainly depends on the precision of the curvature of the disk. No matter whether the satellite dish antenna is elliptical or rectangular, the common satellite dish antenna includes a curvature with a focus point. As shown in FIGS. 1 and 2, a flange 20 is disposed around the periphery of the bottom rim 11 of the arc dish body 10. A folded support ring 30 is formed at the upper portion of the flange 20. As shown in FIGS. 1 and 2, the support ring 30a is formed by bending the upper portion of the flange 20 toward the outside. As shown in FIGS. 3 and 4, another support ring 30b is formed by bending the upper portion of the flange 20 toward the inside. No matter which support ring 30 is used, the satellite dish antennas have to be placed in a flat position when they are packed into a container for transportation out of factory. As shown in FIGS. 2 and 4, the bottom rim 11 of the dish body 10 and the flange 20 are designed in a wide angle. When the upper dish body 10 lies on top of the lower dish body 10, the support ring 30 of the lower dish body 10 is in contact against an end point 12 of the bottom rim 11 of the upper dish body 10, no matter whether the support ring 30 of the lower dish body 10 is bent toward the outside 30a or inside 30b. The support ring 30 of the dish body 10 is an arched surface such that the upper dish body 10 tends to slip down to the ground and damage when subject to the vibration or placed in an improper position. Besides, the conventional dish bodies 10 occupy much vertical space H1 when piled up together, thereby increasing the transportation cost due to the requirement of a larger container. All of the above-mentioned problems are urgently required to be resolved by the related manufactures. SUMMARY OF THE INVENTION Therefore, it is a primary object of the invention to provide a rim structure of a satellite dish antenna that includes a flange with a receiving groove that is recessed inwardly. In this way, the upper dish body can fit into the lower dish body, thereby ensuring a stable stacking structure and saving the stacking space. In addition, the satellite dish antenna can be protected against damage due to slipping down to the ground. Meanwhile, improper stacking to occupy the limited container space can be avoided, thereby saving much transportation cost. In order to reach the above-mentioned objects, the invention includes: a) a dish body; and b) a flange disposed around the periphery of the dish body, a folded support ring being formed at an upper portion of the flange, wherein the flange between the bottom rim of the dish body and the support ring includes a receiving groove that is recessed inwardly, whereby the receiving groove of the upper dish body is disposed on the inner rim of the support ring of the lower dish body when several dish antennas are laid on top of one another so that the dish antennas fit into one another when they lie on top of one another. BRIEF DESCRIPTION OF THE FIGURES FIG. 1 is a cutaway view of a conventional rim structure of a satellite dish antenna; FIG. 2 is a schematic drawing showing the conventional satellite dish antennas in accordance with FIG. 1 in stacked position; FIG. 3 is a cutaway view of another conventional rim structure of a satellite dish antenna; FIG. 4 is a schematic drawing showing the conventional satellite dish antennas in accordance with FIG. 3 in stacked position; FIG. 5 is a perspective view of a first embodiment of the invention; FIG. 6 is a cutaway view of the first embodiment the rim structure of the invention; FIG. 7 is a schematic drawing showing the satellite dish antennas in accordance with FIG. 6 in stacked position; FIG. 8 is a cutaway view of a second embodiment of the rim structure of the invention; FIG. 9 is a schematic drawing showing the satellite dish antennas in accordance with FIG. 8 in stacked position; FIG. 10 is a schematic drawing showing a third embodiment of the satellite dish antennas in accordance with the invention in stacked position; and FIG. 11 is a side view of the invention in stacked position. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 5 through 7, a dish antenna 40 in accordance with a first embodiment of the invention includes a dish body 10 and a flange 20. The dish body 10 is integrally made of metal or plasticizing material so as to form the main body of the dish antenna. The flange 20 is disposed around the periphery of the dish body 10. A folded support ring 30 is formed at an upper portion of the flange 20. The invention is characterized in that the flange 20 between the bottom rim 11 of the dish body 10 and the support ring 30 includes a receiving groove 21 that is recessed inwardly. In this way, the receiving groove 21 of the upper dish body 10 is disposed on the inner rim of the support ring 30 of the lower dish body 10 when several dish antennas 40 are laid on top of one another. In other words, the dish antennas 40 fit into one another when they lie on top of one another. In the embodiment, the support ring 30a is formed by bending the upper portion of the flange 20 toward the outside. As shown in FIG. 7, the bottom rim 11 of the dish body 10 of the upper dish antenna 40 is laid on the inner rim of the support ring 30a of the lower dish antenna 40. In this way, the upper and lower support rings 30 lie on top of one another and are arranged in good order. Accordingly, it is not required to worry about that they are slipped down to the ground or tipped over during the transportation. A second embodiment, as shown in FIGS. 8 and 9, is basically identical to the first embodiment. The same components of the first and second embodiments are marked with same reference signs. The difference lies in that the support ring 30b is formed by bending the upper portion of the flange 20 toward the inside. In this way, the receiving groove 21 of the upper dish antenna 40 is disposed on the top inner rim of the support ring 30b of the lower dish antenna 40 when the dish antennas 40 lie on top of one another. Accordingly, the effect of the first embodiment for avoiding the slip-down risk can be achieved by the second embodiment as well. A third embodiment, as shown in FIG. 10, is basically identical to the second embodiment. The same components of the second and third embodiments are marked with same reference signs. The difference lies in that the flange 20 is slightly formed in an inclined position 22. This embodiment also ensures a practical fitting and positioning effect. As shown in FIG. 11, the structure in accordance with the invention ensures a stable positioning effect and protects against damage due to slipping down to the ground when a plurality of dish antennas 40 lies on top of one another. Meanwhile, the height H2 is considerably reduced by fitting the dish bodies 10 into one another, thereby saving much transporting space in a container and therefore transportation cost. Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims. I CLAIM :- 1.

The invention relates to a rim structure of a satellite dish antenna, and
more particularly to a structure that ensures a stable piling action by providing
a rim disposed around the periphery of the dish body and recessed outward the
inside.
2. Description of the Related Art
In the past, wireless communications on ground are usually affected by
factors such as landforms and constructions, atmospheric layer, curvature of
the earth, and electromagnetic field of the space, so that normal radio waves of
communications are reflected, refracted and diffracted to give rise to poor
communication effect and quality.
Thereafter, a communication satellite is introduced to overcome the
shortcomings of traditional wireless communications, and an earth station
including a dish antenna, a feedhorn, a low noise amplifier (LNA), a down
converter, and a satellite is a major electronic means for receiving satellite
signals, and thus radio wave signals transmitted by a satellite in a space orbit
can be received effectively.
A dish antenna is a window for the whole earth station and its appearance
looks like a dish, but its structure is actually in a parabolic shape for facilitating
the focus of weak signals dispersed on the surface of the antenna, so that the
front side of the antenna becomes a single focal point. Such focal point is

usually used as a position for installing a feedhorn, and thus the quality and
structural technology of an antenna is significant to the effect of receiving

Satellite antennas are used for capturing signals from a satellite in the
space and reflecting the signals to a unique focus, but the capability of
capturing signals mainly depends on the precision of the curvature of the disk.
No matter whether the satellite dish antenna is elliptical or rectangular, the
common satellite dish antenna includes a curvature with a focus point.
As shown in FIGS. 1 and 2, a flange 20 is disposed around the periphery of
the bottom rim 11 of the arc dish body 10. A folded support ring 30 is formed
at the upper portion of the flange 20. As shown in FIGS. 1 and 2, the support
ring 30a is formed by bending the upper portion of the flange 20 toward the
outside. As shown in FIGS. 3 and 4, another support ring 30b is formed by
bending the upper portion of the flange 20 toward the inside. No matter which
support ring 30 is used, the satellite dish antennas have to be placed in a flat
position when they are packed into a container for transportation out of factory.
As shown in FIGS. 2 and 4, the bottom rim 11 of the dish body 10 and the
flange 20 are designed in a wide angle. When the upper dish body 10 lies on top
of the lower dish body 10, the support ring 30 of the lower dish body 10 is in
contact against an end point 12 of the bottom rim 11 of the upper dish body 10,
no matter whether the support ring 30 of the lower dish body 10 is bent toward
the outside 30a or inside 30b.
The support ring 30 of the dish body 10 is an arched surface such that the
upper dish body 10 tends to slip down to the ground and damage when subject

to the vibration or placed in an improper position. Besides, the conventional
dish bodies 10 occupy much vertical space H1 when piled up together, thereby

SUMMARY OF THE INVENTION
Therefore, it is a primary object of the invention to provide a rim structure
of a satellite dish antenna that includes a flange with a receiving groove that is
recessed inwardly. In this way, the upper dish body can fit into the lower dish
body, thereby ensuring a stable stacking structure and saving the stacking space.
In addition, the satellite dish antenna can be protected against damage due to
slipping down to the ground. Meanwhile, improper stacking to occupy the
limited container space can be avoided, thereby saving much transportation

In order to reach the above-mentioned objects, the invention includes:
a) a dish body; and

11 of the dish body 10 of the upper dish antenna 40 is laid on the inner rim of
the support ring 30a of the lower dish antenna 40. In this way, the upper and
lower support rings 30 lie on top of one another and are arranged in good order.
Accordingly, it is not required to worry about that they are slipped down to the
ground or tipped over during the transportation.
A second embodiment, as shown in FIGS. 8 and 9, is basically identical to
the first embodiment. The same components of the first and second
embodiments are marked with same reference signs. The difference lies in that
the support ring 30b is formed by bending the upper portion of the flange 20
toward the inside. In this way, the receiving groove 21 of the upper dish
antenna 40 is disposed on the top inner rim of the support ring 30b of the lower

dish antenna 40 when the dish antennas 40 lie on top of one another.
Accordingly, the effect of the first embodiment for avoiding the slip-down risk
can be achieved by the second embodiment as well.
A third embodiment, as shown in FIG. 10, is basically identical to the
second embodiment. The same components of the second and third
embodiments are marked with same reference signs. The difference lies in that
the flange 20 is slightly formed in an inclined position 22. This embodiment
also ensures a practical fitting and positioning effect.
As shown in FIG. 11, the structure in accordance with the invention
ensures a stable positioning effect and protects against damage due to slipping
down to the ground when a plurality of dish antennas 40 lies on top of one
another. Meanwhile, the height H2 is considerably reduced by fitting the dish
bodies 10 into one another, thereby saving much transporting space in a
container and therefore transportation cost.
Many changes and modifications in the above-described embodiments of
the invention can, of course, be carried out without departing from the scope
thereof. Accordingly, to promote the progress in science and the useful arts,
the invention is disclosed and is intended to be limited only by the scope of the
appended claims.
