| Abstract: | This paper presents mathematical model of dual Y junction stripline circulator fitting for universal WYE junction disk resonator by eigenvalue theorm. Geometry parameters of dual Y junction subjected to stated situations were optimized using inner point solutions method integrated by improved POWELL means. The frequency behaviors of the planar resonator matched with transformers are analyzed. The developed CAD/CAA software can be used easily to design, optimize and analyze octave planar WYE junction or dual Y junction stripline circulators. |
