Broad-band millimeter-wave E-plane bandpass filters
Abstract
In connection with increasing activities related to millimeter-wave integrated circuit development, the E-plane filter has recently drawn considerable attention. In this filter, metal strips are inserted along the E-plane of a rectangular waveguide. Many E-plane filter designs are currently limited to narrow bandwidths of less than a few percent. For wide-band designs, it is necessary to conduct an accurate analysis procedure, which takes into account the interaction of the dominant mode, and in addition, the interaction of the higher order modes generated at the edge of the strips. Shih et al. (1983) have developed a computerized (CAD) algorithm for a class of E-plane filters. The present investigation is concerned with an accurate method which uses an explicit formula to obtain the element values of a distributed low-pass prototype element derived by Rhodes (1980).
