Embodiment Construction

[0014] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0015] like Figure 1~2 As shown, the present invention is a wide-area antenna, including a receiver support rod 4, a reflective surface 2 and a substrate 1, one end of the receiver support rod 4 is fixed on the middle of the substrate 1 through a universal axis A, and around the middle of the substrate 1 Four cardan shaft supports 4 are provided; the reflective surface 2 includes several polygonal reflectors, and the edges of the reflectors are connected to the cardan shaft supports 4 through cardan shafts B; Metal foils 5 are also attached between the edges of the plates.

[0016] If the reflection angle of the antenna needs to be adjusted, it is only nece...

Abstract

The invention relates to a wide-area antenna. The wide-area antenna comprises a receiver supporting rod, a reflecting surface and a base plate; one end of the receiver supporting rod is fixed to the middle part of the base plate through an universal shaft A; N universal shaft supporting seats are arranged about the middle part of the base plate; the reflecting surface comprises a plurality of polygonal reflecting plates of which the side edges are connected with the universal shaft supporting seats through a universal shaft B; the supporting rod is a telescopic rod. According to the wide-area antenna, the receiver supporting rod and a reflecting plate are both connected through the universal shafts, and thereby, the universal adjusting of the whole signal receiving reflecting mechanism is realized, and the adjusting space is larger than that of the traditional satellite antenna.

Description

technical field [0001] The invention relates to a wide-area antenna and belongs to the field of satellite antennas. Background technique [0002] The traditional pot-type reflective antenna has a fixed reflective surface, limited steering range, and poor adjustment performance. When encountering different working conditions, it can only be replaced with antennas of different specifications. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the technical problem of poor adjustment performance of the pot-type reflective antenna in the prior art, and provide an antenna with a relatively wide adjustable range. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A wide-area antenna, comprising a receiver support rod, a reflective surface and a substrate, one end of the receiver support rod is fixed to the middle of the substrate through a gimbal axis A, and N g...
