Abstract
A novel and efficient coupling method has been devised for the design of a low-loss quasi-optical open resonator filter. The method uses a narrow slot opening in the coupling waveguide. An insertion loss of less than 1 dB was achieved for the passband. The resonant slot has been shown to be an efficient means for coupling power into and out of a Fabry-Perot resonator. The filters should have applications in many millimeter-wave and submillimeter-wave systems.<>
