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.
