摘　　要：无人机作战飞机(UCAV)快速发展的同时,无人机平台天线的频率选择表面(FSS)技术也得到广泛应用。设计和测试了一种用于无人作战飞机天线隐身的多层频率选择表面,多层频率选择表面通带为K频段,并且有一个很宽的阻带。数值结果和测试结果验证了该频率选择表面的有效性。该设计技术可以广泛应用在今后无人作战飞机天线隐身上,也可以用在其他隐身平台的相关天线设计中。With the rapid development of unmanned combat aerial vehicle （ UCAV ） , the frequency selective surface（FSS） technique has been widely applied for the antennas of unmanned combat aircraft vehicle. This paper describes the design and measurement of a multi-layer FSS in order to reduce the radar cross section（ RCS） of the antennas of UCAV. The proposed FSS has the pass-band centered at K band and al-so wide out-of-band rejection. Numerical results and measured results show the efficiency of the proposed FSS. The technique proposed in this paper can be widely applied in UCAV 爷 s antenna stealth and other stealth platforms ＇ antenna design.
