This paper presents a metasurface (MS) with broadband low radar cross section (RCS) and investigates its application on antenna. The MS is composed of polarization-dependent artificial magnetic conductors (PDAMCs) for backscattering cancellation. By orthogonally arranging the PDAMCs in a fencelike configuration, the scattering beam is deviated from specular direction, so that the MS achieves RCS reduction over a broad frequency band. As a potential application, the MS is employed to simultaneously promote the radiating and scattering performances of a slot antenna. Full wave simulations and measurements confirm that the novel antenna achieves broadband RCS reduction and significant gain enhancement compared with a reference antenna with metallic ground.
