对非均匀介质块梳状线谐振腔间的耦合进行了理论分析，提出了一种新型的适于移动通信用的微波带通滤波器结构。这种滤波器是把１／４波长的、相同端短路的梳状线谐振腔安置在一小室中。用矩量法对于４种滤波器的耦合形式进行了数值分析。计算均匀和非均匀情况下，奇偶模激励的（ｔｒａｎｓｖｅｒｓｅｅｌｅｃｔｒｏ－ｍａｇｎｅｔｉｃ，ＴＥＭ）场得到谐振器的电容参数的理论值，且ＴＥＭ谐振线之间的耦合系数利用容性参数进行表示。给出了电容耦合系数、电感耦合系数和总的耦合系数的理论值并进行了比较，计算结果显示了理论值和实验值的一致性。
The coupling between comb-line resonators in heterogeneous dielectric blocks is theoretically analyzed, and a new microwave band-pass filter structure suitable for mobile communications is proposed. This filter is the 1/4 wavelength, the same end of the comb-line resonant cavity placed in a small chamber. The moment method is used to analyze the coupling form of four kinds of filters. The theoretical values of the capacitance parameters of the resonator are obtained in the transverseelectro-magnetic (TEM) field under uniform and non-uniform conditions, and the coupling coefficients between the TEM resonance lines are represented by the capacitive parameters. The theoretical values of the capacitive coupling coefficient, the inductive coupling coefficient and the total coupling coefficient are given and compared. The calculated results show the consistency of the theoretical and experimental values.
