Abstract : Navigation with Indian Constellation (NavIC) applications, receiver antenna has to resonate at one or more of NavIC bands L1(1575 MHz), L5(1176 MHz) and S (2492 MHz) bands. Here prototypes of Single Band, Dual Band and Triband antennas are designed and validated for NavIC frequencies. Single band (L5–band) antenna of low cost and electrically small size is simulated and verified. A double band antenna for L1 and S band designed and fabricated is improvised with its return loss and Gain parameter
