An 'H' shaped dual band micro-strip patch antenna array is designed, simulated and fabricated for Global Positioning System (GPS) receivers covering L1 and L5 frequencies of 1.575GHz and 1.176GHz respectively. Antenna parameters like return loss, VSWR, impedance matching, radiation pattern and directivity are analyzed. The designed antenna has a bandwidth of 1.3% and 2.2% for GPS L1 and L5 receivers respectively. In addition to it, the micro-strip patch antenna array is fabricated using co-axial feed mechanism and tested.
