本文从理论和实验两方面研究了铁氧体回转器电路周期结构在一般分布常数线路上加载时的传输特性。提出了三种类型的回转器电路周期结构：周期回转器电路的基本结构、串联电容加载的准LH回转器电路和并联电容加载的准LH回转器电路。提出了一种用电阻代替并联电容的周期性隔离电路结构。利用等效电路模型推导了回转器电路的散射参数。从色散曲线出发，讨论了后向波的左手传输特性。实验中使用的周期性结构的介质微带线和回转器电路制作在铁氧体基板上。从理论上讨论了具有宽带非互易特性的实验结果。
This paper treats transmission characteristics of periodic structure of ferrite gyrator circuit with both theory and experiment, which is loaded into usual distributed constant line with and without lumped capacitor. Following three types of periodic structure of gyrator circuit are proposed: basic structure of periodic gyrator circuit, quasi-LH gyrator circuit with series capacitance loading, and quasi-LH gyrator circuit with parallel capacitance loading. Moreover, replacing the parallel capacitance with a resistance, a periodic structure of isolator circuit is proposed. Scattering parameters of gyrator circuit are derived with help of equivalent circuit model. Left handed transmission behavior of backward wave is discussed from dispersion curves. Experiments were undertaken using periodic structure of dielectric microstrip line and gyrator circuit fabricated on the ferrite substrate. Experimental results having wide band nonreciprocal characteristics are discussed with theory.
