Double-layer broadband circular polarizer based on fission transmission of linear polarization for ku-band applications

A double-layer broadband circular polarizer based on fission transmission of linear polarized (FTLP) for Ku-band applications is presented. Firstly, the novel approach of "fission transmission of linear polarization" is introduced to investigate the polarization transformation behaviour (giant CD effect and optical activity) for linear-to-circular polarization. The designed structure achieves broadband circularly polarized wave with asymmetric transmission (AT) wave emission under the principle of (FTLP). The proposed structure achieves a right-handed circularly polarized (RHCP) wave at 13.94-15.70 GHz, respectively. The axial ratio bandwidth of 11.76% is obtained from 13.94 to 15.70 GHz. The simulated and measured results exhibit good correspondence.
