Performance Analysis of Microstrip Triangle Patch Antenna Using FR-4 Substrate

The microstrip patch antennas are used in various applications for the high performance in the wireless communication system. The simple method is designed and analysis of triangular shape microstrip antenna by varying FR-4 substrate with CST (Computer Simulation Technology) to obtain various results. We have taken the rectangular substrate FR-4 of dimension 77 mm. The antenna operates between 5 GHz to 25GHz range. The design of an antenna is described and simulated results for the main parametrs like return loss, directivity, and radiation patterns are discussed. These antenna is useful for the applications like UMTS, ISM. .
