摘　　要：随着无线通信技术的发展,圆极化天线可接收任意极化的来波,已逐渐成为一种重要的数据传输方式。而对于一些原有的线极化卫星地面站,想要把原有单独线极化馈源网络升级改造成兼容圆极化的馈源网络,就需要更换馈源网络,成本较高。为此提出一种可利用原有线极化馈源网络,通过增加后端配件即可实现的线极化扩圆极化低成本改造方案,此方案已成功应用于某项目,可为同需求用户提供参考。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.
