Miniaturizing a Microstrip Antenna Using Metamaterials and Metasurfaces [Antenna Applications Corner]

A smaller microstrip antenna design is essential for current and future wireless applications. For the design proposed in this article, researchers achieved size reduction when a circular microstrip patch is loaded with a metamaterial structure using a complementary split ring resonator (CSRR) with partially loaded nonuniform metasurfaces (NUMSs) on a ground plane. The designed antenna achieved a size reduction of 74% compared to a conventional...
