Dual Band Rectangular and Circular Slot Loaded Microstrip Antenna for WLAN/GPS/WiMax Applications

In the present work the rectangular micro strip antenna is loaded by triple rectangular slot and dual circular slot. This slot loaded antenna provides dual frequency band. In first frequency band (1.29-1.67GHz) the bandwidth of antenna is 25.675% and in second frequency band (2.02-2.92GHz) the bandwidth of antenna is 36.437.Since the micro strip antenna suffers from narrow bandwidth hence the present work provide an alternative solution to increase the bandwidth. The proposed slot loaded Micro strip antenna is fed by 50? Micro strip feed line. The proposed antenna is simulated by IE3D Zealand simulation software based on method of moments.
