Abstract:
1. A waveguide filter comprising: a monoblock of dielectric material defining a longitudinal axis and including a plurality of exterior surfaces including first and second opposed and spaced-apart exterior top and bottom surfaces extending in the same direction as the longitudinal axis, first and second opposed and spaced-apart exterior side surfaces extending in the same direction and on opposite sides of the longitudinal axis, first and second opposed and spaced-apart exterior end surfaces extending in a relationship normal to the longitudinal axis, and at least a first through-hole; at least a first slit defined in the first exterior side surface and extending a first distance into the monoblock; at least a second slit defined in the second exterior side surface in a relationship opposed and co-linear with the first slit in the first exterior side surface and extending a second distance into the monoblock different than the first distance that the first slit extends into the monoblock; and a step defined in a corner of at least one of the first and second exterior end surfaces of the monoblock of dielectric material, the first through-hole terminating in a first opening in one of the exterior top and bottom surfaces and a second opening in the step.
