Design and analysis of CPW-Fed microstrip patch antennas for wide band applications

A CPW-Fed microstrip patch antenna of size 21×22×1.6 mm

along with its three variants is proposed in this paper. Two slots are introduced on the patch of the base antenna to study the antenna parameters, in terms of bandwidth, gain and directivity for analysis. The proposed antennas are suitable for wireless wideband applications roughly between frequency ranges of 4 GHz to 14 GHz approximately. All three antennas are showing good return losses, high bandwidth of approximately about 10 GHz, peak gain and directivity of approximately 4 dB. The microstrip antenna structures are configured on FR4 epoxy substrate. The configurations are simulated and analyzed using Ansys HFSS software. This study would be helpful in the designing of compact microstrip antennas with enhanced bandwidth for various purposes in the field of wireless communications in general and various earth science applications in particular at super high microwave frequency.
