    摘要： The invention relates to a radio frequency filter comprising at least two helix resonators (HX1-HX2) placed at a distance from each other, each of which is wound of a metal wire into a cylindrical coil. A conductor (MLIN2), preferably a microstrip line, runs between two neighboring resonators and is provided at a distance (d1, d2) from each of the resonator coils so that one part (3) of it is electromagnetically connected to one resonator (HX 1) and the other part (4) is electromagnetically connected to another resonator (HX2).

    摘要： A radio-frequency filter (400, 500, 600) comprises a base plate (401, 603) and an electrically conductive ground plane in connection with it, a predetermined number of inner conductors (403A-403G, 501, 502, 601) attached substantially perpendicularly to the base plate which have a first end and second end, and an electrically conductive casing (402, 503, 602) which is connected at one side to the base plate and substantially surrounds said inner conductors. A first end of each inner conductor is in contact with said ground plane and a second end is in contact with said electrically conductive casing so that the resonators comprising the inner conductors, ground plane and casing function as half-wave resonators.

    摘要： A coaxial resonator filter (1', 50, 50', 50") comprises a dielectric boardlike element (11, 51, 51") and on its surface at least one electrically conductive element (17, 19, 20, 21, 52) to provide an electromagnetic coupling to at least one coaxial resonator (3, 53). The dielectric boardlike element may be the same as the filter's base plate, in which case its outer surface comprises a continuous earth plane (55), or it may be parallel to a separate electrically conductive base plate (56). Link (17), tap (19) and capacitive (20) coupling elements can be realized on the surface of the dielectric board.
