In this paper, the authors are analyzing a two-concentric microstrip patch antenna for GPS application. In the literature survey, most of the literatures are available on different types of antennas, but few publications are available on microstrip patch antenna for GPS application. Microstrip patch antennas are very compact and low in cost. The concentric array has high directivity when compared to the linear array and this concept is applied to the microstrip patch. They are able to obtain low return loss. In view of that, they are designed a concentric circular microstrip patch antenna.
