Abstract

A broadband metamaterials (MTM)-based hexagonal patch antenna is designed and presented. A hexagonal shape of a top patch on a mushroom structure makes not only direct-current paths between two ends of the patch but also round-current path along the outside of the patch, thereby widening a resonance frequency of the mushroom MTM antenna. Moreover, input microstrip transmission line acted as a reflecting element for the surface wave, resulting in forward-directed end-fired radiation. The hexagonal patch was implemented by utilizing a composite right-and left-handed (CRLH) transmission line. The antenna operates from 15.9 GHz to 30.6 GHz covering the Ku- To Ka-band. The antenna gain is from 6 dBi to 9.3 dBi with small size compared to the conventional antennas. The application areas are in automotive radars and ground penetrating radar (GPR).
