A Novel Low-Profile Dual-polarized Planar Array Antenna Using Metasurface

In this paper, we propose a novel low profile dual-polarized high gain microstrip array antenna based on metasurface. It is composed of a top metasurface, bottom metallic ground plane, and two microstrip antennas with orthogonal polarizations, which combines the functionalities of both folded transmitarray and Febry-Perot resonant cavity antenna. Owning the appealing features of high gain, low profile, simple structure and dual polarized operation, our designed antenna will be a promising candidate in the future communication systems.
