Embodiment Construction
[0041] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0042] The present invention uses a four-aperture side-fed biased Cassegrain antenna to realize the equalization of the transmitting and receiving beams, the equalization of the edge beams and the center beams of the coverage area, and its structure is as follows figure 1 shown, including four standard side-fed biased Cassegrain antennas 1 ( figure 1 In A, B, C, and D), the four side-fed biased Cassegrain antennas 1 are in the standard form, and they are shared by transceivers. Each antenna is composed of a main reflector 2, a sub-reflector 3, a feed assembly 4, a first deployment mechanism 11 and a second deployment mechanism 12, and the main reflector 2 and the sub-reflector 3 are connected through the second deployment mechanism 12 , the main reflector 2 is connected to the satellite through the first deployment mechanism 11, and each feed s...
