A new 1-bit configurable phase array antenna based on ‘ancient coin-like’ metasurface

Abstract

Due to the low price, high efficiency and flexible manipulations, the metasurface has attracted more attentions. This paper proposes a new 1-bit configurable reflection array antenna with 11*11 unit cells. The unit cell in the metasurface, which is integrated with one PIN diode, shaped as ‘ancient coin’ can generate reflection phases between 165°-195° (180°±15°). The new phase array antenna can realize flexible manipulations to EM (electromagnetic) waves.
