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.
