Abstract

The design and performance of a stepped slot printed monopole antenna in the ultrawideband is presented in this article. Multiple resonances generated by the stepped slot geometry are matched in the ultrawideband using a modified microstrip feed. The impedance bandwidth (SWR < 2) of the antenna is from 3 to 11 GHz. Radiation patterns are stable and omnidirectional with appreciable gain throughout the band. Performance of the antenna is also analyzed in the time domain, which reveals good pulse handling capabilities. Compact geometry of the antenna allows easy commercial deployment. © 2009 Wiley Periodicals, Inc.

In this paper, we propose a frequency-notched ultrawideband (UWB) slot antenna. The proposed antenna can cover the entire UWB band and the IEEE 802.11a frequency band can be notched out by inserting a hat-shaped slot into the antenna. The path loss ͉S 21 ͉ and group delay are measured and discussed.
