Abstract

A compact and simple design of a printed antenna for ultra-wideband (UWB) application with band-notch characteristics are presented.The antenna size is 30 × 36 × 0.4 mm3 and operates over an extremely wide band of 2.82–13.95 GHz. The desired band-notched UWB operation can be obtained by choosing the size of the inverted L-slit. The proposed design consists of an inverted L-slit as the radiator and a coplanar ground plane. The proposed antenna has advantages of low cost, compact size, thin substrate, and easy design. The measured impedance bandwidth defined by VSWR ≤ 2 of 11.13 GHz (2.82–13.95 GHz), with the band-notched of 4.85–6.04 GHz, is obtained. Moreover, omnidirectional radiation patterns with appreciable gain across the operating band can be obtained. © 2011 Wiley Periodicals, Inc.
