摘要： There is disclosed a dielectric resonator (18; 28) in which a groove (15; 25) is formed in an upper surface (12; 22) of a resonator body (11; 21) adjacent to an outer periphery of a through hole (14; 24) formed through the body (11; 21), and an electrically-conductive film (17; 27) on the inner surface of the groove (15; 25) is electrically connected to an electrically-conductive film (17; 27), formed on the inner peripheral surface of the through hole (14; 24), via an electrically-conductive film (17; 27) formed on a portion of the upper surface (12; 22) of the body lying between the groove (15; 25) and the through hole (14; 24). Thanks to the provision of the groove (15; 25) having the electrically-conductive film (17; 27) formed on its inner surface, the length of the body (11; 21) can be reduced.

摘要： An antenna duplexer has a transmission input terminal, a receiving output terminal, an antenna terminal in which a transmission output terminal and a receiving input terminal are used in common, a transmission filter having at least one resonance element set between the transmission input terminal and the transmission output terminal and coupled by a coupling element, a receiving filter having at least one resonance element set between the receiving output terminal and said receiving input terminal and coupled by a coupling element, and an impedance variable element connected to the resonance element of the transmission filter and the resonance element of said receiving filter respectively in parallel, wherein the frequency transfer characteristic of the transmission filter and the frequency transfer characteristic of the receiving filter are controlled by applying control signals and thereby changing the impedances of the impedance variable element.
