    • Embodiments of the present invention provide a coaxial filter (20). The coaxial filter (20) comprises a first port (21), a second port (22), at least two capacitor segments (231; 232; 233; 234; 235) each having two metal layers (2311, 2313; 2313, 2323; 2323, 2333; 2333, 2343; 2343, 2353) and a dielectric layer (2312; 2322; 2332; 2342; 2352) between them, and at least one grounded inductor stub (241; 242; 243; 244) connected to a metal layer of the at least two capacitor segments (231; 232; 233; 234; 235). The at least two capacitor segments (231; 232; 233; 234; 235) are coaxially connected in series between the first port (21) and the second port (22). An axis (VAX1; VAX2; VAX3; VAX4) of the at least one grounded inductor stub (241; 242; 243; 244) is vertical to an axis (HAXl) of the at least two capacitor segments (231, 232, 233, 234, 235).
    • 本发明的实施例提供一种同轴过滤器(20)。 同轴滤波器(20)包括第一端口(21),第二端口(22),至少两个电容器段(231; 232; 233; 234; 235),每个具有两个金属层(2311,2313; 2313,2323 ; 2323,2333; 2333,2343; 2343,253)和它们之间的电介质层(2312; 2322; 2332; 2342; 2352),以及至少一个接地电感器短截线(241; 242; 243; 244) 所述至少两个电容器段(231; 232; 233; 234; 235)的金属层。 所述至少两个电容器段(231; 232; 233; 234; 235)串联在第一端口(21)和第二端口(22)之间。 所述至少一个接地电感器短截线(241; 242; 243; 244)的轴线(VAX1; VAX2; VAX3; VAX4)垂直于所述至少两个电容器段(231,232,233,244)的轴线(HAX1) 234,235)。
