  4. Abstract:
  5. In this paper, a single-fed, circularly-polarized printed antenna with an elliptical slot for S-band application is suggested. The antenna structure includes a circular patch radiator having one rotated elliptical slot which feeds through a microstrip line. The circular polarization is obtained by adjusting the major axis of the elliptical slot. A metallic circular ground and four 80° slices of a wide ring-shaped patch surrounding the main radiator improve impedance matching bandwidth and circular polarization performance. The suggested antenna has a left-handed circularly polarized (LHCP) with an acceptable axial ratio that is in agreement with S-band applications. For verification of the presented concepts, the designed antenna is suggested together with the simulation and measurement data. The proposed antenna exhibits very good agreement between the measured data and simulation results. © 2022 IEEE
