Abstract: The paper presents a broadband micro strip patch antenna for wireless communication. Conventional inset-fed rectangular patch antenna was designed, simulated, analyzed to improve on its bandwidth. A micro strip patch antenna consists of a radiating patch on one side of a dielectric substrate and ground plane on the other side. The patch is made of conducting material such as copper or gold and it can take any possible shape. Patch antennas have narrow bandwidth. To enhance these narrow bandwidth edge-cut techniques is used to 160MHz. The other antenna parameters like return loss, voltage standing wave ratio (VSWR), and the gain were equally improved. This technique also ensures that the antenna is suitable for mobile wireless communication applications. High frequency structure simulator (HFSS) software is used for the design and simulation the result of this patch antenna. The designed antenna is good for WiMAX technology.
