Design of Planar Microstrip Patch Antenna with Slot using Different Substrates for GPS Application

Now a day, communication market has emerging with new technology and services. Due to demand of markets, there are required to specific and new design of antenna which is smaller in size. In this paper, the microstrip antenna design is specific application for GPS. This antenna has several advantages in terms of smaller in height, chip, fabrication is easy etc. In this paper, the design of microstrip patch antenna for GPS application with slot technique using different substrates (FR4 & RT Duroid) is construct and simulate it. Analysis is done on the two different substrates [(i) FR-4, εr = 4.3 & (ii) RT Duroid, εr = 2.2]. Using high frequency structural simulator (HFSS), this antenna design is simulate and analyzed various parameters likes Gain, Bandwidth (BW), Voltage Standing Wave Ratio (VSWR) & Return loss etc.
