In this paper, a design of I-slot cut rectangular patch microstrip antenna for L-band applications is proposed. The antenna is designed using FR4 glass epoxy as a substrate with permittivity 4.4 and thickness 1.6 mm. The designed antenna has a resonating frequency of 1.57 GHz. The proposed antenna based on co-axial feed configuration has reflection coefficient (return loss) -17.03 dB, gain 5.14 dBi, VSWR 1.32 and cross polarized value (XP) is -40.2 dB over the span of ±500. Good return loss, antenna gain and radiation pattern characteristics are obtained in the frequency band of interest. Structural dimensions of the proposed antenna are optimized by using HFSS simulator
