This receiver operates at L1(1575.42 MHz) frequency band for GPS signal, L5(1176.45MHz) and S-Band (2492.028MHz) for IRNSS signals. The NavIC receiver is expected to receive RF signal with omni-directional coverage. To cater this two antenna element are mounted on outer surface of launch vehicle in diametrically opposite direction. RF Signals from two antenna elements are combined through a power combiner and fed to NavIC receiver. An equal-split Wilkinson power combiner is designed and fabricated. Designed power combiner meets the specifications at all three frequencies. Also the measured insertion losses are better than −3.3dB between the ports. Good amplitude & phase balance is obtained from the circuit. Realization aspects, simulated and measured results are discussed in this paper.

A 27 mm 3 27 mm patch is designed and a slot of 20 mm 3 20 mm is made on it. Slots improve the bandwidth at the cost of introduction of side lobes in the radiation pattern. To absorb these side lobes and to enhance the gain, EBG mushroom structures were introduced. The whole structure when simulated provides a gain of 4.1 dBi and an impedance bandwidth of 721 MHz around 4.8 GHz and 1,200 MHz around 7.6 GHz. Measured results shows good agreement with the simulated results and thus validates this design.
