Design of Circularly Polarized Microstrip Patch Antenna with Inserting of Shorting Pins

This report proposes that for high bandwidth circular polarization microstrip patch antenna along with single-feed is used. On the orthogonal, diagonal of the patch radiator set of pins are placed symmetrically, shorting pins bring Shunt inductive effect. To enhance the electrical size of the patch resonator and to optimize its bandwidth and other parameters in this MP A (microstrip patch antenna) the resonating frequency of the disputed mode is the progressive tune-up. The maximum bandwidth of circular polarization investigates the optimal inserting position. A single pair of internal pins is moderately moved to neatly divide the two disputed modes to get CP radiation. LHCP (left hand circular polarization) or RHCP (right hand circular polarization) perhaps got by varying the feed position along the x and y-axis. After executing extensive analysis, simulation outcomes exhibit a good correspondence and hence prove that the bandwidth is improved from 23MHz to 46MHz, displaying 23MHz (100%) enhancement.
