N2 - A compact circular waveguide polarizer with higher order input mode (TM01) is presented in this paper. The proposed design consists of a triangular metallic plate for TM01-TE11 (linearly polarized) mode conversion and metallic posts loading for linear TE11 to Circular TE11 polarization conversion. The structure is simulated in CST Microwave Studio. Axial ratio is below 3dB and conversion efficiency is above 90% over a bandwidth of 3.28-3.72 GHz. The relative bandwidth is 12.9% (440 MHz) at the operating frequency of 3.4 GHz. The design is purely metallic and calculated high power microwave capability is upto 146 MW. The compact size, light weight structure, high efficiency and high power capability of the polarizer makes it suitable for airborne and portable High Power Microwave (HPM) systems and Space applications.
