A planar 60GHz antenna for MIMO/diversity applications

Abstract

A novel printed 60-GHz antenna for MIMO/diversity applications is presented in this paper. This antenna consists of two coplanar waveguides (CPW) feeding triangle-shaped radiating element for orthogonal radiation pattern and a rectangle stub is inserted at 45°between them to achieve high isolation. The antenna is prototyped using RO5880 printed-circuit board. Experimental result shows that the antenna impedance bandwidth for S11<-10dB is 54.5GHz to 63.1 GHz including the majority 60-GHz working band. The compact size of 5.5mm*5.5mm indicates that the proposed antenna is a candidate for mobile WPAN systems.
