摘要

本文提出了一种基于接地螺旋谐振器的紧凑型多层双带和三带滤波器。滤波器是在两个堆叠基板上实现的:Taconic CeR-10基板和Kapton箔，其中馈线位于上层，而谐振器位于馈线和地之间的中间层。所提出的双频滤波器工作频率为0.68/0.82 GHz，而使用附加四分之一波长谐振器实现的三频滤波器工作频率为0.634/0.81/1.1 GHz。谐振器的特定几何排列导致三个传输零点提供高选择性的通带和高抑制的通带直到第二谐波。

Compact multilayer dual-band and tri-band bandpass filters using grounded spiral resonators

In this paper, a compact multilayer dual-band and tri-band filters based on grounded spiral resonators are proposed. The filters are realized on two stacked substrates: Taconic CeR-10 substrate and Kapton foil, where the feeds are positioned in the upper layer whereas resonators are placed in the middle layer between feed lines and the ground. The proposed dual-band filter operates at 0.68/0.82 GHz while tri-band filter, realized using addition quarter-wavelength resonators, operates at 0.634/0.81/1.1 GHz. Specific geometrical arrangement of the resonators result in three transmission zeros providing high selectivity of the passbands and high suppression out of the passband up to the second harmonics.
