Title:
FILTER
Document Type and Number:
WIPO Patent Application WO/2018/199036
Kind Code:
A1
Abstract:
The purpose of the present invention is to make it easy to design a filter having the desired characteristics. The filter (1) comprises a plurality of electromagnetically coupled resonators (10-50)。 Each of the two resonators that are coupled with each other from among the resonators (10-50) is disposed so that D < R1 + R2, where R1 and R2 represent the radii of circles circumscribing the wide walls of the two resonators and D represents the distance between the centers of the two resonators.
