    • A resonant unit and a filter are provided. The resonant unit includes: a dielectric substrate; a metal microstrip disposed on a plane of the dielectric substrate, where the metal microstrip is used as a signal input/output port; and a defected ground structure disposed on another plane opposite to the plane of the dielectric substrate, where the defected ground structure includes a ground loop and an interdigital structure located inside the ground loop, the interdigital structure includes multiple fingers, and the ground loop or at least one finger in the interdigital structure includes at least one embedded interdigital structure. Harmonic suppression capabilities of the resonant unit and the filter can be improved, and an area can be reduced.
    • 提供谐振单元和滤波器。 谐振单元包括:电介质基板; 设置在所述介质基板的平面上的金属微带,所述金属微带用作信号输入/输出端口; 以及布置在与介质基板的平面相对的另一平面上的缺陷接地结构,其中缺陷接地结构包括接地环路和位于接地环路内部的交叉指型结构,交指指型结构包括多个指状物,并且接地环路或 叉指结构中的至少一个指状物包括至少一个嵌入式指状结构。 可以改善谐振单元和滤波器的谐波抑制能力,并且可以减小面积。

    • Conventional coaxial wiring devices present a problem in that the management of the manufacturing process therefor is difficult. A coaxial wiring device according to the present invention includes a first member, a second member, and a conductor plate. The first member (10) and the second member (30) include, when a line that connects a first port and a second port is denoted by a reference line, a first groove (11) that has a central point on the reference line and extends in a direction that intersects with the reference line; a second groove (12) that connects one end (FN1) of the first groove (11) and the first port; a third groove (13) that connects the other end (FN2) of the first groove (11) and the first port and has a shape that is line symmetrical to the second groove (12) with respect to the reference line; a fourth groove (14) that connects one end (FN1) of the first groove (11) and the second port; and a fifth groove (15) that connects the other end (FN2) of the first groove (11) and the second port and has a shape that is line symmetrical to the fourth groove (14) with respect to the reference line.
    • 传统的同轴布线装置存在难以对其制造过程进行管理的问题。 根据本发明的同轴布线装置包括第一构件,第二构件和导体板。 第一部件(10)和第二部件(30)在由基准线表示连接第一端口和第二端口的线时包括具有基准线上的中心点的第一槽(11)和 在与参考线相交的方向上延伸; 连接第一槽(11)的一端(FN1)和第一端口的第二槽(12) 第三槽(13),其连接所述第一槽(11)的另一端(FN2)和所述第一端口,并具有相对于所述基准线相对于所述第二槽(12)线对称的形状; 第四槽(14),其连接第一槽(11)的一端(FN1)和第二端口; 以及连接第一槽(11)的另一端(FN2)和第二端口的第五槽(15),并具有相对于基准线与第四槽(14)线对称的形状。
