A design theory is described for all kinds of E-plane waveguide filter circuits, and a general matrix equation is presented. Both higher order-mode interaction and finite thickness of the inserts are considered. EFLTR, a commercial software package, is developed for filter designs. Various E-plane circuits are analyzed and two metal insert E-plane filters are designed using this package. The results show good agreement with published or experimental results.
E-plane waveguide filter circuits, presented by Konishi in 1974,[1] are high Q, low cost and suitable for mass production. These filters have been used widely in microwave and mm-wave bands. The circuits are ...
