High‐gain broadside dipole planar AMC antenna for 60 GHz applications

Abstract

A novel 60 GHz high‐gain planar artificial magnetic conductor (AMC) antenna is proposed. The prototype of the antenna is a dipole structure with a broadband input impedance match. Parasitic patches and a novel AMC plane are successively used to enhance its broadside gain. The antenna has a compact size of 7.5 mm × 8 mm, including the modified AMC plane. Simulated and measured results both show the antenna has good properties of return losses better than 10 dB, stable peak gains up to 10.9 dBi and favourable radiation patterns from 57 to 64 GHz, which all denote that it is fit for 60 GHz wireless portable communication systems.
