A rectangular antenna, to work in the operating frequency of L band is designed with capacitive disc fed for GPS application. The antenna gain aimed to have 2dBi. The capacitive disc is utilized for the increment of impedance bandwidth. It is designed using CADFEKO 7.0 and obtained the output with improved bandwidth and good return loss. Moreover, much improved reflection coefficient of the proposed antenna is obtained and it has been analyzed. With reference to simulation results, reflection coefficient at 1.13 GHz is attained as -34.18 dB with bandwidth of 140 MHz and at 1.34 GHz is -26.13 dB with the bandwidth of 230 MHz.
