    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=100mm的模型,验证了这种全极化可调方案的正确性.

    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.
