Document Type and Number:
WIPO Patent Application WO/2024/080820
Kind Code:
A1
Abstract:
The present invention relates to a filter for a communication device, and in particular, can simplify the complexity of the filter and achieve the performance of various filters due to comprising a notch forming unit that restricts a filtering frequency area by forming prescribed notches at the left end and right end of a passband, wherein the notches are disposed closer than the separation distance between adjacent resonance elements at a portion in which magnetic field coupling between the resonance elements is dominant or a portion in which electrical field coupling between the resonance elements is dominant among at least three adjacent resonance elements sequentially selected along the longitudinal direction of a cavity for multipath coupling.
