U-shaped printed monopole antenna

Abstract

Studies have been carried out on broadband printed square monopole antenna with microstrip line feed and results are presented here. Simple way has been demonstrated to show the effects on radiation due to position of surface current and the effect of central part of patch on the impedance- bandwidth of the printed square monopole antenna. For VSWR < 2 the bandwidth obtained is 60% for the center frequency of 2 GHz. Experiment has been carried out to validate simulated result.
