In this article, a novel ultra‐wideband (UWB) wide‐slot antenna with dual band‐notched characteristics is proposed. The original UWB antenna is composed of a fork‐shaped feed structure and a ground plane with a quasi‐semicircular slot. The 5.2‐/5.8‐GHz wireless local area network notched bands are realized by the introduction of modified mushroom‐type semicircular electromagnetic band‐gap structures. The antenna is etched on a 35 × 35 mm 2 substrate. The measured results show that the proposed antenna achieves a wide impedance bandwidth (VSWR < 2) from 2.73 to over 12 GHz with dual notched bands (VSWR > 2) covering 4.55–5.46 GHz and 5.68–6.35 GHz successfully. © 2012 Wiley Periodicals, Inc.
