Aperture Coupled Patch Antenna for Dual Band Operation 4.5/5.5 GHz

This manuscript presents, the analysis of aperture coupled microstrip antenna for 4.5/5.5 GHz band is proposed using method of moment. The designed antenna stricture is represented to its equivalent circuit diagram. The equivalent circuit has been used for obtaining its reflection coefficient and VSWR. The theoretical result obtained is compared with simulated result and there are in close agreement. It has been observed that radiating structure resonate at dual frequencies i.e., 4.5 GHz and 5.5 GHz with frequency ratio of 1.22.
