Summary:
A single-layer circularly polarized (CP) substrate integrated waveguide (SIW) square ring-slot antenna at X-band is proposed in this letter. By using two shorted square ring-slot in the top wall of SIW and two shorting vias, the CP wave is obtained. To verify the design method, the SIW antenna is fabricated and measured. The measure impedance bandwidth and AR bandwidth are 11% (9.62-10.74GHz) and 1.2% (10.08- 10.2GHz), respectively. The antenna also has good radiation pattern and high gain than other similar SIW antennas.
