Comparative Study of the Performance of Microstrip Circular Patch Antenna With and Without Slots

In this paper, the authors report on the simulation studies of microstrip circular patch antenna with and without slot. The antennas have been designed for 2-8GHz frequency band. Bakelite with dielectric constant of 4.5 has been chosen as substrate. The feed locations of (3.5, 1) and (1, -9.5) are the optimized values for circular patch without and with slots respectively. It has been observed that the BW increased slightly in the case of slotted patch and antenna efficiency remains almost constant for both cases.
