| 摘 要： | 平板抛物面（flat parabolic surface 简称FLAPS）天线是九十年代出现的一种大口径天线形式。FLAPS 天线
在性能上最主要的缺陷就是窄带，一般情况下其带宽小于5％，对电大口径短焦距馈电时更窄。本文设计并制作出一种由
C 波段和Ku 波段两个反射面天线组成的2m×2m 薄膜双频平板抛物面天线，两个频段的天线共用一层膜面。对该天线的电
性能进行了测试，测试结果表明：该天线两个频段的相对带宽均大于8％（副瓣电平≤-18dB）。

| Abstract: | The main limitation to flat parabolic surface antenna performance is the narrow bandwidth, generally lower than
5 percent and even less for large flat parabolic surface antenna. In this paper, the double frequency and wideband flat parabolic
surface antenna was designed, fabricated and tested, which comprised of two coplanar C waveband reflecting surface antenna
and Ku waveband reflecting surface antenna. Testing results indicate that the frequency bandwidth can reach 8% for sidelobe
level less than or equal to -18dB.. |
