Design of Planar Microstrip Patch Antenna for GPS Application

The ever increasing demand of communication equipment and the emergence of new technologies require an efficient design of antenna that is of smaller size for range of frequency such as GPS. Because of the various advantages like low profile, ease of integration, low cost etc. microstrip antenna found vast application in communication system. Here we report the investigation on planar microstrip patch antenna for GPS and other wireless application using probe feed technique. Analysis is done on the two different substrate that is the FR-4 and RT Duroid 5880 with dielectric constant 4.3and 2.2 respectively. The antenna is simulated using HFSS v2012 and the antenna parameter like return loss, VSWR, Gain, Bandwidth would be analyzed. The design procedure for planar microstrip patch antenna for GPS and other wireless application is illustrated.
