Abstract :
The authors propose an evanescent-mode wave-guide filter consisting of two parallel cutoff waveguide paths with dielectric resonators. They introduce an accurate design method incorporating both the full-wave analytical method and the impedance inverter method. The specified overall characteristic is then synthesized with the help of a computer-aided design method. Measurements on several kinds of filters modeled at X-band show excellent agreement with the designed characteristics
