Abstract:
A coaxial cavity resonator comprising:walls delimiting a cavity (12) having side walls (13), a top wall (14) and a bottom wall (15) opposing said top wall, at least one cylindrical conductive body, comprising a conductor rod (16) and a main conductor disc (17), in said cavity (12), an end (16a) of said conductor rod (16) being connected to a first side (17a) of said main disc (17), a free end (16b) of said conductor rod (16) being in short-circuit connection with said bottom wall (15) of said cavity (12), and a second side (17b) of said main disc (17), opposite to said first side (17a), being in open-circuit relation with said top wall (14) of said cavity (12), characterised in thatsaid cavity (12) further comprises one or more conductive main plates (21, 51) electrically coupled to the side walls (13) and out of galvanic contact with the conductive body (11, 31), and said main plate(s) (21, 51) being located between the main disc (17) and said side walls (13), at the first side (17a) of the main disc (17).
