Circular Patch Antenna with Defected Ground and Parasitic Layer for Wide Bandwidth

In this paper, the authors present a modified circular microstrip patch antenna fed by a coaxial probe. The proposed paper makes use of parasitic layer and defected ground to improve the bandwidth of the antenna. IE3D version 12 is used to simulate the proposed work. Simulation result shows that the antenna resonates at 3.73GHz and 5.07GHz frequencies with improved bandwidth of 22.68%. The antenna showed a huge increase in the bandwidth of 1.150GHz for center frequency 5.07GHz and 290MHz bandwidth for center frequency 3.73GHz.
