This paper presents an improved substrate integrated non-radiative dielectric (SINRD) bandpass filter design. The LSE₀₁ (Longitudinal Section Electric) mode is used as fundamental mode, which allows substrate height reduction compared to classical lowest LSM (Longitudinal Section Magnetic mode). A new modelization is proposed to characterize such a bandpass filter using the circuits equivalent method. Simulation results are successfully compared to finite element software results. In the design, permittivity choices are justified through a sensitivity analysis to meet the bandpass filter requirements. Finally, the SINRD bandpass filter is synthesized by drilling an air hole pattern in the dielectric substrate. This new filter is characterized by simulations and measurements.

LSE01基模SINRD带通滤波器的模态模型与设计

本文介绍了一种改进的基板集成非辐射电介质 (SINRD) 带通滤波器设计。LSE ₀₁（纵向截面电）模式用作基本模式，与经典的最低 LSM（纵向截面磁模式）相比，它允许基板高度降低。提出了一种使用电路等效方法来表征这种带通滤波器的新模型。仿真结果成功地与有限元软件结果进行了比较。在设计中，通过灵敏度分析来证明介电常数选择的合理性，以满足带通滤波器的要求。最后，SINRD 带通滤波器是通过在介电基板上钻一个气孔图案来合成的。这种新滤波器的特点是模拟和测量。
