C波段机载共形导航天线

一种C波段机载共形导航天线

内容简介：本文利用短路探针加载的方式设计了一款小型化共形椭圆形微带导航天线,较常规的微带天线,该天线辐射贴片面积减小了80%左右.采用耐高温材料作为天线介质板及天线罩,同时使用特殊焊接方法使得天线具有良好的耐高温性能.实测天线在要求角域内增益大于-0.5dB,方位面不圆度小于1dB,具有良好的电气性能.

Abstract：@@@@A miniaturized microstrip elliptic antenna is designed by a way of short-circuit probe loading. Comparing with a conventional microstrip antenna, the antenna reduces about 80% in the size of radiation patch. It has good capability of resistant to high temperature because its dielectric substrate and radome are made of high temperature materials and welded using special method. The antenna has good electrical performance in test date, with the gain greater than -0.5dB in the required angle and the un-roundess of pattern less than 1dB.
