A novel design for broadband radar cross‐section (RCS) reduction and a high gain waveguide slot antenna is proposed. The orthogonal array of a polarisation‐dependent artificial magnetic conductor (AMC) is exploited and contributes to the scattering and radiation improvement. The measured results demonstrate that, compared with the conventional antenna with a metallic plate, the novel antenna achieves a 20% relative bandwidth of 10 dB RCS reduction and 3.2 dB gain enhancement.
