摘要
The present invention relates to a cavity type wireless frequency filter having a cross-coupling notch structure, the filter comprising a notch substrate provided for cross-coupling between at least two resonance elements among a plurality of resonance elements, wherein the notch substrate comprises: a main substrate, which is made of a non-conductive material and has the first and second coupling structures mechanically coupled with at least two resonance elements, respectively; and a conductive line which is implemented by a conductive pattern formed on the main substrate and transfers a signal of a first resonance element to a second resonance element by using a non-contact coupling method.
