| 中文摘要
|
| 提出了一种新的基于多层回折线结构的VICTS天线极化实现方式，首次采用两个回折线极化器级联的方式，以一个统一的极化器结构，在一副VICTS天线上实现线极化补偿和线/圆极化转化功能.天线无需更换极化器，即可实现线极化和圆极化的自由切换.设计了一个直径D=100mm的模型，验证了这种全极化可调方案的正确性. |

|
| 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. |
