With the development of wireless communication,circularly polarized antennas can receive waves of arbitrary polarization,gradually becoming an important transmission method.For some existing linearly polarized satellite ground stations,if they want to upgrade and transform their separate linearly polarized feed network into a feed network compatible with circular polarization,they need to replace the feed network,which is costly.This article proposes a low-cost transformation scheme that can utilize the original linear polarization feed network and expand circular polarization by adding backend accessories.This solution has been successfully applied to a certain project and can provide reference for users with similar needs.
