Abstract
Official abstract text for this publication.
A method of tuning the frequency of a waveguide filter including the step of removing dielectric material from one or both of the first and second opposed exterior side surfaces of the waveguide filter to cause a change in the center frequency of the waveguide filter. In one embodiment, dielectric material is removed from one or both of the first and second opposed exterior side surfaces of the waveguide filter in unequal amounts wherein the tuned waveguide filter includes first and second slits defined in the respective first and second opposed exterior side surfaces which extend unequal first and second distances into the body of the waveguide filter.
First claim
Opening claim text (preview).
I claim: 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 e…
