The Indian regional navigational satellite system (IRNSS) is an autonomous regional satellite navigation system being developed by the Indian Space Research Organization (ISRO) which would be under complete control of the Indian Government. The requirement of such a navigation system is driven by the fact that access to Global Navigation Satellite System, GPS is not guaranteed in hostile situations. Design of IRNSS antenna at user segment is mandatory. The simulated Microstrip patch antenna operates on the frequency of L5 band (1176.45 MHz) which is used for positioning services. Its parameters are enhanced by making 2x8 array with Teflon substrate, increasing gain, directivity, and efficiency to 17.3dB, 18.1dBi and 95.58% respectively. For fabrication purpose substrate FR4 substrate can be used for which 10.1dB gain and 15.4dBi directivity is obtained till 2x8 array. Results of simulation are compared with hardware results using Vector network analyzer for two models of all array.
