In this paper, we share our experience of designing a circularly polarized square patch antenna at L band. The antenna is designed using a relatively cheap substrate FR-4 with permittivity r = 4:4 and loss tangent tan = 0:02. The antenna has a gain of 5dB. Simulated response shows that the designed antenna has an input impedance(Zin) of 50 approximately. An efficiency of 65% is obtained for a single patch. It has a narrow bandwidth and a high Q factor. The design procedure, feed mechanism and simulation results are presented in this paper.
