    • A multi-mode cavity filter, comprising: a dielectric resonator body incorporating a piece of dielectric material, the piece of dielectric material having a shape such that it can support at least a first resonant mode and a second substantially degenerate resonant mode; a conductive layer substantially covering the dielectric resonator body but having one or more apertures therein allowing access to the dielectric resonator body; and a coupling structure arranged in an aperture of the one or more apertures, comprising at least one coupling path for at least one of coupling an input signal to the first and second resonant modes and coupling an output signal from the first and second resonant modes, the coupling path having an open-circuit end located adjacent to an edge of the aperture for controlling a strength of electric field generated by the coupling structure.
    • 一种多模式空腔滤波器,包括:介质谐振器本体,其结合有一片电介质材料,所述介电材料片具有使得其能够支撑至少第一谐振模式和第二基本上简并谐振模式的形状; 导电层,其基本上覆盖介质谐振器体,但在其中具有一个或多个孔,允许接近介质谐振器本体; 以及布置在一个或多个孔的孔中的耦合结构,包括至少一个耦合路径,用于将输入信号耦合到第一和第二谐振模以及耦合来自第一和第二谐振模的输出信号中的至少一个, 耦合路径具有位于孔的边缘附近的开路端,用于控制由耦合结构产生的电场的强度。
