摘要：
This article presents a band-notched planar slot antenna presented to overcome interference with some already existing standards such as the 1EEE802. 11a and HYPERLAN/2 systems. The slot antenna, evolved from an elliptical aperture antenna, is fed by CPW with all elliptical tuning-stub to achieve UWB characteristics. This slot antenna, using open-end slits oil the tuning stub or a pair of parasitic strips ill the aperture, is then designed to reject the sub-hand between 5 and 6 GHz. Practical structures are fabricated and the measured results show that this antenna not only retains all ultrawide bandwidth bill also has band-rejection capability. In addition, its radiation pattern preserved the omni-directional feature, meeting the UWB system requirements. (C) 2009 Wiley Periodicals, Inc.
