Abstract

A compact ultrawideband (UWB) microstrip-fed slot antenna with dual band-notched function is presented.The prototype consists of an L-shaped microstrip line, a modified ground plane with T-shaped slot and a small stub embedded on the ground for impedance matching. The designed antenna satisfies the return loss requirement of larger than 10 dB in UWB frequency range from 3.1 to 10.6 GHz, whereas shows the wireless local area network and worldwide interoperability for microwave access band notched in the frequency band of 5.1–6 GHz and 3.5–4.1 GHz by the inserted rectangle strips. Detailed analysis and experimental results for the design are studied and investigated. © 2010 Wiley Periodicals, Inc.
