Analysis of Various Patch Antennas against Proposed Dual Polarized Patch Antenna

Using dual polarization we can effectively increase the efficiency of reception and reduce the bit error rate as the receiver gets an option for the signal to be received, it dynamically selects out of the available dual polarized signals which has better quality. Dual polarized transmission and reception can be achieved through a single micro strip antenna thus the input infrastructure required does not change significantly and hence the overall cost change is insignificant compared to the benefits achieved. In a signal receiver when such a signal with dual polarization is demodulated using luhns algorithm the system gets two signals with vertical and horizontal polarizations. In this work, the proposed antenna acts as a receiver as well as a transmitter surpassing its predecessors in the areas of effective power by 18 %, effective area 23 %, directivity 15 % and radiated power by 26 %. Hence, a very effective antenna with easy manufacturing technique which can use already existing 48Nm technology is achieved, with overall efficiency of 84.78 %.
