Loss reduction in antenna for with feedline

This paper presents modified patch antenna for 3 GHz operating frequency. Here different approaches are studied by changing feed position. Simulation is done using IE3D software for various parameters. Return loss of final design was - 26.43 dB for 3 GHz frequency and VSWR of 1.10 over -12.10dB of conventional design. Phase difference of almost 180 degree is achieved between transmitter and receiver terminal. Proposed antenna was fabricated giving different details. Here both simple and modified antennas are fabricated. Measured and simulated results are reported.
