Dual Band Dual Polarized Ring Resonator Loaded Slot Antenna for Low RCS Applications

This work proposes orthogonal circular polarized, double band slot antenna with combination of Split Ring Resonator and complementary Split Ring Resonator for a low radar cross-section applications. The proposed low RCS antenna has return loss bandwidth of 1.76 GHz and 0.5 GHz with maximum gain of 4.2 and 3.3 dBi in band -1 and band-2 respectively. The better reduction in RCS of 20 dB is achieved.
