COMPACT MICROSTRIP-FED ANTENNA FOR ULTRA-WIDEBAND APPLICATIONS

Abstract

A novel printed monopole antenna for ultra-wideband (UWB) applications is presented, which is composed of wide slot and Y-shaped microstrip feed line with a pair of inverted-L-shaped notches. The prototype with an overall size of 26 mm× 30 mm× 2 mm achieves good impedance matching, constant gain, stable radiation patterns, and a relative impedance bandwidth of 110.6% is achieved, which covers 3.09–10.74 GHz.
