发明背景 1.发明的范围本发明阐述能有选择地抑制副瓣的天线装置,重点研究这样的天线装置,它的主天线包括主反射器和馈电嗽叭,而副瓣抑制装置有两种。(1)至少有两个辅助天线,每个辅助天线包括一个预定口径的反射器和馈电喇叭。这个喇叭发射的信号和主天线发射的相同,且具有合适的幅度和相位。辅助天线配置在主天线两侧的对应边上,在被抑制副瓣的平面内其距离近似等于主天线口径的边缘之距。(2)主天线
BACKGROUND OF THE INVENTION 1. Scope of the Invention The present invention sets forth an antenna device that selectively suppresses sidelobes, focusing on antenna devices whose main antenna includes a main reflector and a feed horn, and two side-lobe suppression devices . (1) At least two auxiliary antennas, each auxiliary antenna including a reflector of predetermined aperture and a feed horn. The signal emitted by this speaker is the same as the one transmitted by the main antenna and has the proper amplitude and phase. The auxiliary antennas are arranged on the corresponding sides on both sides of the main antenna at a distance that is approximately equal to the distance of the main antenna aperture in the plane of the side lobes to be suppressed. (2) the main antenna
