Abstract :
This study introduces a novel method to reduce the radar cross section (RCS) of wideband antennas. A novel wideband radar absorbing material (RAM) with frequency selective surfaces (FSSs) is proposed. The wideband RAM is used as the ground plane of a Yagi-Uda and a Vivaldi antenna for in-band RCS reduction. The measurement result shows that the radiation pattern of the antennas over the whole band is preserved when wideband RAM is used. The RCS of the Yagi-Uda and Vivaldi antenna with RAM can be reduced by more than 10 dB over the operating band with this method.
