Circular Antenna UWB Microstrip Line Feeding Planar Modified

In this paper we have investigated
compact printed semicircular disc monopole
antenna, which is basically printed microstrip
antenna with etched ground plane for UWB
applications. In particular we have simulated
very compact semicircular disc monopole
antennas for UWB communication. Simple
rectangular microstrip line is used for feeding the
printed monopole antenna and its frequency
bandwidth under -10dB return loss is ranging
from 3GHz to 11.6 GHz. This compact printed
monopole antenna works well for the whole
UWB frequency band 3.1-10.6GHz.
