Abstract

This paper introduces a novel implementation technology for realizing dual-band bandpass filtering responses using high- $Q$ slotline resonators with self-packaged multilayer configuration. The concept of a 3D slotline is introduced, which utilizes the innovative metal-integrated suspended line (MISL) technology. This technology utilizes an all-metal structure, effectively eliminating dielectric loss. Furthermore, the implementation of an encapsulated structure significantly reduces radiation loss in the slotlines. Thus, the $Q$ factors are greatly improved. Based on MISL, a dual-band bandpass filter with wideband responses and multiple transmission zeros was designed, fabricated, and tested based on 3D cascaded-mode half-wavelength resonators. The test results demonstrated a high level of consistency with the simulation results, confirming the high- $Q$ characteristics of the proposed 3D slotlines.

自封装多层全金属集成悬浮式槽线双频滤波器

本文介绍了一种新颖的实现技术，利用自封装多层配置的高 Q 值槽线谐振器实现双频带通滤波响应。本文引入了三维槽线的概念，利用了创新的金属集成悬浮线（MISL）技术。该技术采用全金属结构，有效消除了介质损耗。此外，封装结构的实施还大大降低了槽线的辐射损耗。因此，Q $Q$ 因子大大提高。在 MISL 的基础上，设计、制造并测试了一种基于三维级联模式半波长谐振器的具有宽带响应和多个传输零点的双频带通滤波器。测试结果与仿真结果高度一致，证实了所提出的三维槽线具有高 Q 值的特性。
