| 摘 要： | 为了研制自动跟踪同步通信卫星平板相控天线阵系统，对相控阵天线中的关键元件单环非互易铁氧体移相器进行了研究。利用双平板模型推导出了单环非互易铁氧体移相器的超越方程，并对其特性进行了讨论。根据超越方程对单环非互易铁氧体移相器的差相移随铁氧体厚度的变化进行了数值计算。结果表明随铁氧体厚度的增加，它的差相移增加。

| Abstract: | The single toroidal non-reciprocal ferrite phase shifter that is the key components of a phase array antenna is studied to develop the phase array antenna for autotracking synchronous communication satellite. The transcendental equation for the single toroidal non-reciprocal ferrite phase shifter is obtained by using the twin slab model, and its properties are discussed. The differential phase shift changes as the change in the thickness of the ferrite phase shifter is calculated with the transcendental equation. The results show that the differential phase shift increases with the increase in the thickness of the ferrite slab and the increase becomes gradual when the thickness increases to certain values. |
