Performance Evolution of Reconfigurable Antenna Using Contact and Non Contact Feeding Technique

The major demand need of wireless communication are less weight, optimization in cost and antennas with Small height that are adequate of obtaining high efficient performance over a frequencies of wide range. Micro-strip patch antennas are widely used for the range of 2 to 4 GHz (S-band) frequencies. Antenna design and simulation was done using HFSS (High Frequency Structural Simulator). Generally these antennas uses different feeding techniques like Micro Strip Line, co-axial and proximity, aperture coupled feeds. The proposed reconfigurable rectangular microstrip patch antenna has been tested using Co-axial, Aperture coupled Feed Techniques to improve the antenna parameters like Frequency and VSWR, Return Loss.
