In this article, a novel compact UWB antenna with dual band‐notched characteristics is proposed. The original UWB antenna is realized by etching an open‐slot on the ground plane. The 5.2‐ and 5.8‐GHz WLAN rejected bands are achieved by inserting a slot on the ground plane and a slot‐type split ring resonator inside a circular exciting stub on the front side, respectively. The antenna has a compact structure with an area of 16 × 27 mm 2 . The small size makes it an excellent candidate for UWB operation. Prototype of the antenna are fabricated and tested. The simulated and measured results show that the proposed antenna achieves a wide impedance bandwidth (VSWR < 2) from 2.92 to over 12 GHz, and the dual rejected bands (VSWR > 2) are 4.85–5.37 GHz and 5.68‐5.98 GHz. Radiation patterns and antenna gains are also given in this article. Detailed design steps, parametric studies and experimental results for the antenna are investigated in the following section. © 2012 Wiley Periodicals, Inc.
