An accurate real time positioning system is very important parameter. The requirement of indigenous regional navigational satellite system is driven by the fact that access to Global Navigation Satellites System, like global positioning system (GPS) is not guaranteed in hostile situations. The design of frequency reconfigurable microstrip patch antenna is mandatory to overcome the crucial situations. The proposed reconfigurable microstrip patch antenna is used to switch the frequency between L5 band (1.17 GHz) and S band(2.49 GHz). The reconfigurability for the designed antenna is achieved by incorporating RF PIN diode between the radiating elements and resonance slot which has a low-profile structure with maximum gain of 8.51dB and with low cross polarization of approximation <-30dB. In this project, review of the frequency reconfigurable microstrip patch antenna for IRNSS application has presented.
