Abstract

PURPOSE:To simplify the construction and to make the directivity adjustment of an antenna easy, by supporting the antenna at four points and constituting a support as a struts arranged in triangle shape. CONSTITUTION:Each one end of struts 15-20 of variable length is freely rotatably fitted to movable supporting metallic fixtures 21-24 fixed to a base at first. Another end of struts 16, 17, 19 and 15, 18, 20 is respectively fitted to movable supporting metallic fixtures 11 and 12, freely movably. A supporting frame 10 is fixed to the metallic fixtures 11, 12. A fitting frame is fitted to the frame 10 via a strut 6 and a supporting rod 61. One end of struts 13, 14 is fitted to a metallic fixture 22 and another end is to two points of the frame 10 freely rotatably, and these two points are fitted to a fitting ring 5 via movable supporting metallic fixtures 8, 9. Next, an antenna is fitted to a ring 5. In the adjustment of the antenna device thus assembled at the directivity to a satellite, the antenna is turned around a straight line H by changing the length of the struts 13 and 14 and around a straight line D by changing the length of the strut 6.

A polar mount type antenna device is rotatably supported around two axes. One axis is parallel to the earth's axis and is called the fixed axis. The other axes are perpendicular to this and are called movable axes. The main axis of the main reflector of the antenna device, that is, the axis that should be directed toward the satellite, is orthogonal to the movable axis. When installing the antenna device, the main reflector is rotated around both axes to direct it to the target satellite.

An antenna device usually consists of an antenna section that has electrical functions, such as an antenna main reflector, and a support section that supports it on the ground and has a mechanism to direct it toward the satellite.In the conventional polar mount system, the antenna section Normally, the main reflector of this type of antenna is circular, so select three points equally spaced in the circumferential direction of this mounting member, for example, the mounting ring, and A fixed axis is provided along the straight line passing through the two points. Therefore, a feed horn or the like protruding from the center of the antenna section to the support section sometimes interferes with the movement of the antenna section when adjusting the pointing towards the satellite. Therefore, in order to secure the space necessary for the movement of this antenna part, the number of support parts was set at four points. Also, when changing the target satellite and adjusting the rotation around the fixed axis, 3
It was not easy because the points needed to be supported at all times.

For example, if you want to point the antenna to a satellite located at Togaku University instead of a satellite that has been in the western sky, you must first stock up) 13
, change the length of 14 and make the straight line horizontal, then strut 1
One end attached to the metal fitting 22 of No. 4 is replaced with the metal fitting 21, and then the strut 13 is also replaced in the same way to adjust its length, and the strut 6 achieves its purpose by just making minor adjustments. You can do it while doing it. Therefore, the antenna directivity range can be doubled compared to the conventional antenna. Moreover, with such a structure, not only the above-mentioned work but also the disassembly of the support part can be carried out by a small number of people without any danger by disassembling it in the reverse order of assembly.
