Design of Low RCS Conformal Discone Antenna Applied to Low-Observable Platform

The antenna usually needs to be embedded into the cavity to achieve a conformal design with the stealth platform, but it often destroys the stealth of the platform. In this paper, a discone antenna is designed, which has good end-fire and omnidirectional radiation performance. The radar cross section (RCS) of the platform is studied after placing the antenna in the cavity of the platform. Through cavity and antenna shape modification, the radar cross section (RCS) reduction can be realized. The effectiveness of the measures is verified by simulation software.
