Summary:This article presents a band‐notched planar slot antenna presented to overcome interference with some already existing standards such as the IEEE802.11a and HYPERLAN/2 systems. The slot antenna, evolved from an elliptical aperture antenna, is fed by CPW with an elliptical tuning‐stub to achieve UWB characteristics. This slot antenna, using open‐end slits on the tuning stub or a pair of parasitic strips in the aperture, is then designed to reject the sub‐band between 5 and 6 GHz. Practical structures are fabricated and the measured results show that this antenna not only retains an ultrawide bandwidth but also has band‐rejection capability. In addition, its radiation pattern preserved the omni‐directional feature, meeting the UWB system requirements. © 2009 Wiley Periodicals, Inc.
