Microstrip U-Slot Aperture Coupled Antenna for Wimax Application

The micro strip antenna has become a rapidly growing area of research with their potential application like mobiles and satellite communication. The antenna exhibits wideband characteristics that depends on various parameters such as U slot dimensions, coupling slot feed etc. In this project, the proposed antenna design shows the measured return loss within acceptable range throughout band (3.15 GHz-3.6 GHz). Feeding technique adapted in aperture coupled. This design is simulated using CST microwave studio software. The main aim of this project is to optimize the gain of 2 dB using a superstreet layer i.e. Lambda/2 distance from ground level and thickness of layer is Lambda/4. The computer simulated results showing VSWR value below 2 in middle frequency band range of WIMAX enhances the adoption of this antenna for WIMAX application. The results are analyzed, estimated and discussed in terms of VSWR and radiation pattern.
