Abstract

Ceramic waveguide filter apparatus is provided including a ceramic body portion with at least one resonating means contained therein and/or associated therewith. The at least one resonating means is capable of undergoing resonance at a particular electromagnetic frequency or frequencies. One or more tuning means are provided with said apparatus for tuning the resonant frequency or frequencies of any or any combination of the at least one resonating means, the apparatus or the coupling between two or more resonating means.
