Abstract:
A metal window filter assembly using a non-radiative dielectric waveguide, comprising:a filter housing which includes parallel conductive plates facing each other; and a filter, disposed between said parallel conductive plates, for filtering a certain frequency band of an electromagnetic wave traveling therethrough, said filter including a plurality of polygonal metal windows and a single body type dielectric line made from a non-radiative dielectric, said dielectric line being formed with a plurality of polygonal inserting grooves which are spaced by the predetermined distance on first and/or second surfaces of said dielectric line making contact with said parallel conductive plates, and said metal windows being inserted in said inserting grooves one to one to form multi-staged dielectric resonators cascaded as a single body, wherein said filter has a filtering function selectively passing the certain frequency band determined by an impedance coupling relationship that said multi-staged dielectric resonators have with respect to the electromagnetic wave.
