In this paper, a compact hybrid coplanar waveguide (CPW) fed 1 × 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. © 2011 Wiley Periodicals, Inc.
