In this paper, the authors 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. They have observed that using slotted patch antenna and using probe feed at proper location they 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, they 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.
