In this article, we use pattern‐diversity technique to combine a RF single‐pole double‐throw (SPDT) switch with an antenna array together in order to reduce the signal distortion caused by multipath fading. In addition, in order to improve the way controlling the SPDT switch by software, a novel circuit structure which will control antenna pattern switching automatically by hardware is also developed. Return loss and radiation patterns are presented and compared with the measured results. Good agreement is achieved between computed and measured results and illustrates the validity of the designed method. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2410–2413, 2013
