摘要

设计并仿真了ka波段大功率、低电压驻波比和插入损耗单环形铁氧体移相器。利用有限元求解器确定并优化了差分相移(DPS)、插入损耗、大功率特性和阻抗匹配。研究了高阶模在结构中传播的影响。在ka波段，在6%带宽下，所有相位的回波损耗均为15dB。

A single toroid nonreciprocal digital latching ferrite phase shifter in grooved waveguide

Ka-Band high power, low voltage standing wave ratio (VSWR) and insertion loss single toroid type ferrite phase shifter is designed and simulated. Differential phase shift (DPS), insertion loss, high power characteristics and impedance matching are determined and optimized using finite element solver in Ansoft HFSS. The effect of high order modes propagating in the structure is examined. <;1.2dB insertion loss and >;15dB return loss is obtained for all phase states in 6% bandwidth at Ka-Band.
