A circular ring-shape monopole on-chip antenna with artificial magnetic conductor

A wideband 60GHz monopole on-chip antenna based on 0.18μm CMOS process with an artificial magnetic conductor (AMC) is presented. The structure of the proposed on-chip antenna consists of a circular ring-shaped monopole antenna fed by a 50Ω coplanar waveguide (CPW). Results show that the proposed circular ring-shaped monopole antenna mounted on AMC plane can offer higher gain, higher radiation efficiency and wider impedance bandwidth, while has a smaller antenna size.
