本文评述航天飞船用的多波束天线,介绍了由16个组合馈源照射直径为3.53米的偏馈抛物面天线在5.925～6.725千兆赫的实验结果。多波束天线原理多波束夭线能同时或按时序产生多个分波束,由此可以合成一个或几个成形波束.单个或多个馈源照射微波
This paper reviews the multibeam antennas used in spacecraft, and presents the experimental results of a parabolic antenna with a diameter of 3.53 meters at 5.925 ~ 6.725 GHz irradiated by 16 combined feeds. Multi-Beam Antenna Principle Multibeam antennas generate multiple sub-beams at the same time or in time sequence so that one or several shaped beams can be combined. Single or multiple sources illuminate the microwave
