Abstract

The design of a planar reconfigurable antenna with bidir- ectional end-fire and broadside radiation patterns from a common aper- ture is presented in this article. The proposed antenna is composed of two series-feed collinear slot subarrays corporately fed by a microstrip line and two series-feed dipole subarrays corporately fed by a microstrip line-to-double side parallel strip line transition, respectively. A prototype for 2.4 GHz wireless local area networks applications is fabricated and measured. The measured realized gains are about 11—12 and 7-8 dBi for broadside and end-fire patterns. Experimental results, which agree with the simulated ones, verify that the proposed antenna is a good can- didate for pattern reconfigurable applications. V C 2014 Wiley Periodicals, Inc.
