带线双Y结环行器设计

The Design of a Stripline Double-Y Junction Circulator

由于双Y结具有尺寸小。频带宽的独特优点,目前已广泛用于带线结环行器设计。本文在本征值理论的基础上,首先讨论带线双Y结环行器的分析方法,分析了影响环行器性能的一些主要因素,给出了主要的分析结果。而后介绍了带线结环行器的设计与优化方法,本文中介绍的设计方法不同于导纳斜率法。

Bceause of its specific characteristics of small size and wide band width,the double-Y or YY junction has been widely used in the design of stripline-junction circulator. On the basis of the eigenvalue theory,the analysis of the stripline double-Y junction circulator is given first. Some main factors that affect circulator properties are discussed,and the main risults are provided in the paper. Then, the design and optimization mithods are introduced. The methods proposed in this paper are different from the admittance slope method proposed by J. Hilszajn and W. Nicbet.
