    摘要: A junction for connecting two waveguides (101, 103) having substantially a 90-degree angular offset between longitudinal symmetry axes of their cross-sections, said junction comprising a first interface (102) and a second interface (104) for connecting said waveguides (101, 103), and further comprising at least a first transformer section (202) and a second transformer section (206), both having cross- sections of substantially rectangular shape, and both having said 90-degree angular offset between longitudinal symmetry axes of their cross-sections, wherein the first and the second transformer sections (202 and 206) are connected in a way that a T- shape connection is formed and the first transformer section (202) has a first protruded ridge (204) on its broad wall (210) and the second transformer section (206) has a second protruded ridge (208) on its broad wall (212), wherein the broad wall (212) with the second ridge (208) is connected to the top narrow wall of the first transformer section (202) and the ridges (204 and 208) are so located that they overlap.

    摘要: In a bandstop filter having an input port (2; 3), an output port (3; 2) and a waveguide (1, 1') connecting the two ports, at least one resonator body (4, 5; 4' 5') is located in the waveguide (1, 1'), which resonator body has resonance frequency above the limit frequency of the waveguide (1; 1').

    摘要: The aim of the invention is to provide a cavity resonator that has a great variable frequency area of a resonance frequency and is provided with good quality. Such a cavity resonator is provided with a round cross-section. The H11n wave mode acting as the resonance wave mode exists in said resonator which is separated into two components with regard to the cross-sectional plane (5) thereof. The two cavity components (1, 2) can be displaced against each other in the direction of the common longitudinal axis (7) thereof.
