Summary:
Metamaterial (MTM) unit-cells with a zero refractive index was developed, characterized and employed for gain enhancement of a Yagi antenna operating at 60 GHz. The unique property of the MTM gathers the wave radiated from the antenna and collimates it towards the normal direction when used as director. The proposed design provides a gain enhancement of 2.3 dB when the nearing zero-refractive-index MTM director is utilized. Simulation results show that the conventional Yagi antenna’s director replaced by the proposed MTM directors can achieve a maximum gain of 8.18 dBi at 60 GHz.
