Design and Simulation of Broad Band Aperture Coupled Microstrip Antenna

Micro strip patch antennas have been widely used in the various applications. The versatility and flexibility in structure offered by micro strip antenna has resulted in improve antenna performance (i.e., bandwidth, gain, efficiency). The paper addresses aperture coupled feed technique of micro strip antenna with multiple feed lines. The proposed micro strip antenna has rectangular and E shape structure for antenna patch with multiple feed lines. The performance of the antenna is evaluated by inserting changes in various parameters (i.e., size of patch, location of slot in patch and ground plane) of micro strip antenna. The return loss, VSWR and radiation pattern are calculated using an soft. It is observed base on the simulation results that proposed antenna design significantly increase the impedance bandwidth.
