Abstract
Radar absorbing material is an indispensable part of a stealth aircraft. It renders the aircraft invisible to radar detection. This paper proposes a wideband dual-substrate frequency selective surface based on quadruple hexagonal split rings as a radar absorber. Such split rings on Rogers RT-5880 constitutes a passband characteristic while ECCOSORB SF with copper patch acts to reduce the transmission. The 90% absorption bandwidths are 5.15 and 4.70 GHz in the X-band for TE TM modes, respectively, at normal incidence. The absorption remains as high as 90% for an incident angle of upto 45ฐ, beyond which the absorption drops slightly to about 80% while the bandwidth is slightly reduced. ฉ 2019 IEEE.
