A meanderlinebased polarizer technique for the implementation of a fullpolarization tunable of VICTS antennas

Abstract:

A new method based on multilayer meanderline structures to implement the expected polarization of VICTS antennas was introduced. A cascade of two meanderline polarizers with a unified structure was employed for the first time, which could achieve the functionality of linear polarization compensation and linear to circular polarization conversationon the same VICTS antenna. Without the need of polarizer replacement, free switch between linear polarization and circular polarization was achievable. A model with the diameter of 100 mm was designed, and the correctness of the fullpolarization tunable scheme was verified.
