Abstract :
A type of dual frequency and dual-circularly polarized antenna was presented in this paper. The stacked dielectric layers and two probes-fed were used to make the dual-frequency and dual-circularly polarized antennas into one antenna´s area. The antenna was simulated by method of moment (MoM) to confirm its parameters. The measurement results showed that the antenna´s performance was matched with simulated. The relative bandwith more than 15% (dual frequency, VSWR≤2.0). The beam gain in 110 degrees is higher than 0dBi; the AR is less than 3dB in band. It has good capability in dual frequency and dual circularly polarized.
