This article presents a novel tree‐shaped antenna with wideband and end‐fire properties designed by the Competitive Algorithm of Simulating Natural Tree Growth. The antenna has an impedance bandwidth of 27.2% for S11 < −10dB, maintains end‐fire radiation pattern and achieves a high gain over the entire frequency band from 5.4 GHz to 7.1 GHz. © 2010 Wiley Periodicals, Inc.
