Abstract :
Printed-circuit patch antennas have been one of the most significant research topic in microwave communication due to their applicability in various domains like seismic data collection and natural resources exploration etc. This paper presents the crux of an elaborate comparative study of different design patterns of circular micro-strip patch antennas with and without geometric slots. A further performance enhancement is suggested by the results obtained by Genetic Algorithm in finding the feed position and impedance matching of the antenna designs. The results obtained from the simulations done in OpenEMS(FDTD method) integrated with MATLAB environment lead to the antenna designs suitable for application in Sat Com, GPS, RADAR, RFID with improved antenna performance in terms of reduced return loss and wide band width.
