Reconfigurable multiband microstrip patch antenna design for wireless communication applications

The proposed work deals with the design of an antenna which can be used for most of the wireless applications by reconfiguring and tuning the antenna. The antenna can be used for various combinations of wireless applications such as Wi-Fi, Wi-Max, 3G within a microwave L, S, C and X frequency bands in Electromagnetic Spectrum. Now days, different antennas are preferred/devised for different wireless applications. The increased complexity and the size of the device are the major issues. Using proposed technique, the selection of frequency band in communication systems can be conveniently served by only one antenna. In this work rectangular patch is designed with U-shape slotted antenna using ADS software and pin diodes are used for reconfiguration i.e. to select different frequency band depending upon wireless application. The main advantage of this design is that it is having low profile, light weight, and easy to fabricate.
