摘要
提出了一种适用于wifi和5G NR FR1频率的多层双带滤波器。为了实现，衬底集成波导(SIW)加载了互补分裂环谐振器(CSRR)。在SIW线截止频率以下实现倏逝模式。放置在不同层的谐振器被调谐和优化以适应工作频率。wifi应用的中心频率为2.4GHz, 5G NRFR1通信的中心频率为3.5GHz。
CSRR-based miniaturized dual band filter in SIW multilayer structure for wifi and 5G NR FR1 applications
A novel multilayer dual band filter designed in wifi and 5G NR FR1 frequencies is proposed. For the implementation, a Substrate Integrated Waveguide (SIW) is loaded with Complementary Split Ring Resonators (CSRR). Evanescent mode is achieve below the cutoff frequency of SIW line. Resonators which are placed in different layers are tuned and optimized to fit the working frequencies. The center frequencies are reached in 2.4GHz for wifi applications and the second one at 3.5GHz for 5G NRFR1 communication.
