The present invention relates to radio frequency filters and a method for adjusting the frequency response of the filter, more particularly to filters having a resonator construction. In the construction in accordance with the invention, the surface currents appearing in the conducting material short circuiting the ends of the resonators, are influenced e.g. by forming patterns to said conducting material, and through that the high frequency characteristics of the short-circuiting connection are influenced, still maintaining a galvanic short circuit between the inner conductors of the resonator.
La présente invention porte sur des filtres radiofréquence, particulièrement des filtres à résonateur, et sur une méthode d'ajustement de la courbe de réponse de ces filtres. Dans la construction de l'invention, les courants de surface circulant sur les conducteurs qui court-circuitent les extrémités du résonateur sont asservis, par exemple, en adoptant des configurations adaptées auxdits conducteurs, et il en résulte que les caractéristiques haute fréquence du court-circuit sont influencées tout en maintenant le court-circuit entre les conducteurs internes du résonateur.
