Optimization and Return loss Reduction Of Micro strip Patch Antenna
An Antenna is one of the essential parts for microwave communication. Since it help both transmitting and receiving the information. An antenna is a device that is made to efficiently radiate and receive the radiated electromagnetic waves. The microstrip antennas have attractive features such as low profile, small size and weight, low cost, printed directly on circuit board and easy to analysis and fabricate. For reduction of return loss, stacked patch and Double U- slot on patch of microstrip antenna concept is used. A rectangular microstrip patch antenna has been investigated and its performance has been analyzed with the aid of Ansoft HFSS version 13.microstrip patch antenna, stacked patch microstrip antenna and double U- slot stacked patch microstrip antenna have been designed for S- band to reduce return loss of antenna.
