Abstract
The invention relates to a frequency filter including a structure with, on one face, two extreme evanescent areas and at least one wave guide area between the evanescent areas. The at least one wave guide area and the evanescent areas form a single closed cavity. The single cavity is partitioned by at least two resonator elements that are embedded in the single cavity at placement areas and that contribute to delimiting the at least one wave guide area and the evanescent areas.
