In this paper, a reconfigurable dual-band circular polarizer structure is proposed. To implement the reconfigurable function of the circular polarizer, a pair of detachable cog-comb plates that determine circular polarization performance are attached to the outside of the circular waveguide. In order to verify the electrical performance of the proposed circular polarizer structure, a dual-band circular polarizer operated in Tx/Rx bands (Tx: 6.25~6.75 GHz, Rx: 3.70~4.10 GHz) is designed for application in the Korea augmentation satellite system Uplink Station (KUS) system. The axial ratio at the bore-sight of a conical horn antenna with an optimized dual-band circular polarizer in series shows good circular polarization performance of less than 0.99 dB at the Tx band and less than 1.50 dB at the Rx band. A lightweight manufacturing method for dual-band circular polarizers is also proposed.
