Performance Analysis of a Planar Array Antenna for Enhancement of Bandwidth for Wireless Communication

The antenna technology with microstrip patch antenna is widely increasing for its compact structure, low cost, lesser size and easy configuration. Microstrip patch antennas with various configuration provides wide range of applications in GPS, GSM, Personal area network, Direct broadcast satellite, radar Wi max Wi-Fi. The frequency range between 3.3 GHz and 3.7 GHz is widely used for wimax application, though the present single patch microstrip antenna system does not provide required gain, directivity and bandwidth. So I thought to work on improving gain as well as bandwidth. For this purpose I thought of making 1x2 planar array of patch for gain increment and then stacking these layers for bandwidth enhancement.
