摘要：In this paper we present a comparative study of cross slot micro -strip patch antenna and T slot coupled microstrip patch antenna, using proposed antenna design and probe feeding at proper position to find the resultant return loss, VSWR and bandwidth. We have observed that using slotted patch antenna and using probe feed at proper location we can get better return loss, VSWR and bandwidth. Some analysis has been presented on a circularly polarized microstrip antenna with T slot configurations & cross slot circular polarized antenna. Here we will study a T-slot coupled circularly polarized microstrip antenna in the frequency 1.575 GHz & cross slot microstrip patch antenna at the same frequency. The upper patch i.e. the radiating patch would be circular. Initially optimized dimension obtained for the antenna which provides satisfactory result further these dimensions of circular patch microstrip antennas are modified to obtain a good directivity as well as impedance matching at frequency 1.575 GHz. By varying the antenna parameters attention is also paid to obtained good axial ratio.
