Multi Band Microstrip Patch Antenna for WiMax and Bluetooth Applications

Microstrip patch antennas have been widely used in a various useful applications, due to their low weight and low profile conformability, easy and cheap realization. In this paper, an attempt has been made to investigate new microstrip antenna structure for Wimax and bluetooth Applications. CST MWS and MATLAB Softwares are used for the simulation and design calculations of the microstrip antennas. The bandwidth, gain, radiation pattern are evaluated[1]. Using CST MWS simulation software proposed antenna is designed/simulated and optimized. The antenna exhibits multiband at 2.402 GHz, 3.635 GHz, 4.333 GHz and4.737 GHz. The multi band nature of the antenna is due to I shaped slot cut in the ground and the various current paths excited in the structure.
