In this paper, the authors describe the wireless microstrip patch antenna i.e. for WiMAX applications. In this paper microstrip line feeding techniques is used. Microstrip line feed is a contacting scheme, in which RF power is fed directly to the radiating patch using a connecting element such as a microstrip line. Paper describing how the bandwidth enhancing by using additional patch element and gives a better understanding of design parameters of an antenna and their effect on return losses, bandwidth, VSWR and resonant frequency.
