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.
