Abstract

ACS fed directional monopole suitable for high data rate communication with simple and compact structure, high gain and heavy bandwidth is presented. Antenna’s bandwidth ranging from 3.8 to 10.29 GHz, with uniformly oriented directional radiation pattern and polarization make it suitable for high data rate communication applications such as ISM5.2 and ISM5.8 WLANs, HIPERLAN2 and HiSWANa. It also covers 95% of FCC specified UWB band too. The peak gain of the antenna is obtained as 7.84 dBi with efficiency greater than 88 %. Electrical equivalent circuit modeling of the antenna is also developed and the results obtained are discussed.
