高介电常数介质陶瓷材料已被应用于制作平面阶跃阻抗谐振器（SIR）微波带通滤波器。滤波器的输入/输出端口由直接接在谐振器上的传输线构成。推导了滤波器等效电路的导纳矩阵，并将其转换为散射矩阵，初步确定了所需的规格。考虑了损耗和其他电磁效应，进一步修改了所设计滤波器的实际尺寸。利用IE3D模拟器对设计的结构进行了仿真。用HP8510B网络分析仪对预制滤波器进行测量。采样结果表明，该滤波器的性能响应与计算机模拟结果吻合较好。©2000 John Wiley & Sons, Inc微波光学学报，26(2):444 - 444,2000。
High-permittivity dielectric ceramic materials have been applied in the fabrication of a planar stepped-impedance resonator (SIR) microwave bandpass filter. The input/output ports of the filter are formed with transmission lines directly tapped to the resonators. The admittance matrix for the equivalent circuit of the filter has been derived and transformed to the scattering matrix to initially determine the required spec. Losses and other EM effects are taken into account to further modify the actual dimension of the designed filter. The designed structures are simulated using an IE3D simulator. Fabricated filters are measured by an HP8510B network analyzer. Sample results of the filter performances demonstrate responses in good agreement with the computer simulations. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 26: 410–413, 2000.
