    • A resonator constituted of an external conductor (1), a dielectric plate (2), a resonating capacitance element, an input terminal (5) and an output terminal (6). The plate (2) is fixed at the upper and lower ends to the upper and lower walls of the conductor (1), respectively. The resonating capacitance element is constituted of electrodes composed of metallic thin layers or metallic plates respectively provided on the front and back of the plate (2). The lower end of one of the electrodes is electrically connected to the lower wall of the conductor (1), and a gap is formed between the upper end of the one electrode and the upper wall of the conductor (1). The upper end of the other electrode is electrically connected to the upper wall of the conductor (1), and a gap is formed between the lower end of the other electrode and the lower wall of the conductor (1).
    • 由外部导体(1),电介质板(2),谐振电容元件,输入端子(5)和输出端子(6)构成的谐振器。 板(2)分别固定在导体(1)的上壁和下壁上端和下端。 共振电容元件由分别设置在板(2)的前后的金属薄层或金属板构成的电极构成。 一个电极的下端电连接到导体(1)的下壁,并且在一个电极的上端和导体(1)的上壁之间形成间隙。 另一个电极的上端电连接到导体(1)的上壁,并且在另一个电极的下端和导体(1)的下壁之间形成间隙。
