Design of New Inset Fed Circular Patch Antenna with Gain Enhancement

This work is focused on a design of a circular patch antenna using a high frequency structure simulator (HFSS). It presents a robust example of design of circular patch antenna, in which we have, simulated and computed by three different feeding configurations in order to improve the parameters and to evaluate the range and the performances of such antennas. The substrate used is RT/duroid 5880 with a dielectric constant of 2.2 having low dielectric loss. The method of analysis considered is the cavity model with antenna having a patch of radius 10.9 mm and a grounded substrate of dimensions 30 mm × 30 mm at frequency of 5 GHz belonging to C band which is used for some Wi-Fi devices and weather radars. Comparison and interpretation of different antennas parameters and specially gains, have been achieved.
