Two-path cutoff waveguide dielectric resonator filters
H. Shigesawa, M. Tsuji, T. Nakao, K. Takiyama
This paper proposes a new type of evanescent-mode waveguide filter consisting of two parallel cut-off waveguide paths with dielectric resonators. We initiate here 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 modelled at X-band show excellent agreement with the designed characteristics.
