Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an aperture of a parabolic antenna, a planar antenna using a microstrip line, a slot line, etc., which constitutes an earth station in communications and broadcasting using geostationary satellites. The present invention relates to a spherical support structure suitable for housing an antenna.

[Conventional technology]

The structure for installing a conventional aperture antenna is based on Japanese Patent Application Laid-Open No. 62-8
As described in Japanese Patent Laid-open No. 1130 or Japanese Patent Application Laid-open No. 179228/1983, an aperture antenna is supported by a pole or the like at a point or by a line.

(As the aperture diameter increases, a large and complex surface support structure is required to maintain the accuracy of the parabolic surface for parabolic antennas and the flat surface for planar antennas.)

In addition, in order to maintain the shape of the surface with high precision even with a small antenna, the surface antenna itself had to be made sturdy.

[Problem to be solved by the invention]

In the above conventional technology, since the aperture antenna is supported by points or lines, as the aperture of the antenna becomes larger, the support mechanism and antenna fixing mechanism to ensure surface accuracy become complicated and large-scale. there were. For this reason, there was a problem that the price of the mechanical parts could not be reduced.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a simple and inexpensive installation structure for an aperture antenna.

[Means to solve the problem]

In order to achieve the above object, the present invention adopts a structure that supports the aperture antenna with a surface, and also adopts a spherical structure to simplify the direction adjustment of the antenna.

By forming the sphere that supports the aperture antenna from a foam material such as urethane or styrene, it becomes possible to reduce weight and cost.

[Effect 1] Since the present invention adopts a structure in which the aperture antenna is supported by a surface, the antenna is supported more easily than the conventional method of supporting it with points or lines, or the method of molding the entire surface with a resin mold or press of a steel plate. , the mechanism for direction adjustment can be constructed from a foam material such as urethane or styrene.

Therefore, the same configuration method can be used regardless of the size of the aperture of the antenna, and weight and cost reductions can be achieved.

〔Example〕

The groove 5 is provided over half the circumference of the great circle of the sphere 1, and its depth is such that the linear elastic body 6 does not extend beyond the spherical surface of the sphere 1.

The support 3 is fixed to the plane part of the hole 4 of the support base 2, and the linear elastic body 6 penetrates the hole through which the linear elastic body 6 passes, and the spherical body 1
The sphere 1 is supported by the spherical portion 7 of the support base 2 while maintaining contact with it by attracting it in the direction of the support base 2 using the elasticity of the linear elastic body 6.

By applying an external force to the sphere 1 and rotating the sphere l in the direction of its great circle, the linear elastic body slides through the hole in the support 3 and rotates while sliding on the spherical part 7 while keeping the sphere 1 attached to the support base. do.

Next, by rotating the sphere 1 around the axis connecting its center point and the support 3, the spherical part 7 is kept attracted to the support base.
Rotate while sliding.

By combining these two rotations, one point on the spherical surface of the sphere 1 can be directed in any direction within the hemisphere, and at the same time, the sphere 1 can be fixed to the support base.
