Broadband Circularly Polarized Antenna Array via Metasurface and Partially Emptied Substrate

A metasurface including an empty region constituted by a square-shaped aperture is proposed to improve the performance of a circularly polarized patch antenna array based on sequential-phase feeding. The metasurface is applied/stacked to a conventional antenna consisting of a loop feeding structure,...
