摘要：

In this paper, a compact hybrid coplanar waveguide (CPW) fed 1 X 2 slot antenna array with radiation pattern diversity is proposed for the wireless local area networks (WLAN) application. The antenna array consists of two rectangular slot radiation elements, two feed slots, a CPW and an open-ended strip. The feed network provides out-phase and in-phase feed with high isolation in a relatively compact structure without any lossy circuits, and difference and sum radiation patterns are achieved in the azimuth plane with wide bandwidths of 480 MHz (20%) and 580 MHz (24.2%). The measured gains of dual-pattern are better than 4.93 and 3.76 dBi in the WLAN band (2.4-2.484 GHz). The proposed dual-port array can be used as pattern diversity in modern mobile system.
