In this article, a simple and compact CPW‐fed planar monopole antenna for ultra‐wideband applications is presented and investigated.The proposed antenna with a small size of 26 mm × 26 mm × 1 mm is composed of a gourd‐like radiation element fed by a CPW feed line, and a modified stair‐style ground. The proposed antenna has been successfully designed, fabricated, and measured. The measured results show that the antenna achieves a wide impendence bandwidth from 3.1 to 15.2 GHz with return loss less than −10 dB. In addition, it exhibits a nearly omnidirectional radiation pattern, stable antenna gain, and good time‐domain characteristics across the operation band. © 2010 Wiley Periodicals, Inc.
