Airborne Communication Antenna Protection and Stealth

In order to reduce the influence of airborne communication antenna system on radar scattering area in aircraft stealth setting, it is necessary to add radome with absorbing characteristics or to add absorbing material outside the radome. However, these measures will have a certain impact on the performance of the antenna. In order to investigate the effect of the coating method of absorbing materials on the antenna performance, a typical L-band communication antenna system is selected in this paper. The structure model of radome is established by CATIA, and the antenna system is simulated by HFSS. The influence of the method of absorbing material and the performance of antenna is revealed, which provides an engineering reference for the design of antenna system and the coating of stealth material.
