Bridged Double U-Slot Microstrip Patch Antenna for Wireless Communication

Abstract

The Micro strip Patch Antenna are widely used in Mobile and Satellite communication, Global Position System Applications, handheld devices etc. Micro strip patch antennas have advantages like light in weight, less volume, inexpensive, small size and ease of fabrication and conformity. Also, the micro strip patch antennas are also capable to provide dual and circular polarizations, dual-frequency operation, broad bandwidth range, etc. Despite the many advantages of micro strip patch antennas, they do have some considerable drawbacks. One of the main restrictions with patch antennas is their naturally narrowband performance due to its resonant nature. So for the antenna miniaturization and bandwidth improvement Bridged double U-slot micro strip patch antenna used. The first is the analysis of single element narrowband rectangular micro strip antenna which operates at the central frequency of 2.39GHz. The second aspect is the analysis and design of slot cut Dual U-shaped micro strip antenna with bridge connection also inserted inverted C shape on ground plane. The simulation process has been done through high frequency structure simulator (HFSS). The properties of antenna such as bandwidth, return loss, VSWR has been investigated.
