A compact coplanar waveguide fed circular wide‐slot antenna with dual‐band‐notched characteristic is proposed by using an arc‐shaped slot (ASS) and an arc‐shaped parasitic element (ASPE) for ultra‐wideband (UWB) communication applications. The center frequencies of the dual‐notch bands can be tuned in a wide range by adjusting the parameters of the ASS and the ASPE. Both the numerical and experimental results show that the proposed antenna can operate over a wide frequency band ranging from 2.7 to 12 GHz with VSWR < 2, with the exception of the two notch bands operating at wireless local area network band and X‐band. In addition, the proposed antenna has a compact size and omnidirectional radiation pattern, which is suitable for UWB communication applications. © 2014 Wiley Periodicals, Inc.
