Method of tuning a planar filter with additional coupling created by bent resonator elements

摘要：

A bandpass planar filter (110) comprises a signal input and a signal output (116), and one or more resonator elements (112, 114) coupled serially end-to-end between the input and the output across gaps (118) that separate the elements from the input, the output, and from each other. The resonator elements form a serpentine shape such that at least two portions of the serpentine shape are positioned side-by-side parallel to each other separated by a spacing (120). The side-by-side portions effect additional coupling between the resonator elements that forms a notch (transmission zero) (204) in the passband (200) of the filter. The input, output, and resonator elements are etched into one surface (106) of a PC board (102); the other surface (104) of the PC board forms a ground plane of the filter, and the substrate (103) of the PC board forms a dielectric of the filter.

摘要（中）：

带通平面滤波器（110）包括信号输入端和信号输出端（116），以及一个或多个谐振元件（112,114），它们跨接在间隔（118）上的输入端和输出端之间端对端地串联连接，来自输入，输出和彼此的元素。谐振器元件形成蛇形形状，使得蛇形形状的至少两部分彼此平行地彼此平行地间隔开间隔（120）。并排部分影响在滤波器的通带（200）中形成陷波（传输零点）（204）的谐振元件之间的附加耦合。输入，输出和谐振器元件被蚀刻到PC板（102）的一个表面（106）中; PC板的另一个表面（104）形成滤波器的接地平面，并且PC板的基板（103）形成滤波器的电介质。
