Abstract

Abstract

In this paper, a new type of circular polarizer is presented. Based on the characteristic of TE11 degenerate modes of circular waveguide and different phase velocities of long and short axes of elliptical waveguide, TE11 mode circular polarizer with elliptical waveguide is developed successfully. According to boundary conditions of microwave transmission, one incident TE11 mode is divided into two orthogonal TE11 modes with same magnitude. By adjusting length of elliptical waveguide, phase difference of two orthogonal TE11 modes is 90°, and conversion from linear polarization to circular polarization is realized. By FDTD software, circular polarizer is designed and optimized. Manufactured circular polarizer was measured by cold test and high-power microwav
