摘要

设计了一种工作在6ghz以下的5G移动通信高选择性双带通滤波器。它由两个具有四个传输零点的折叠开环阶跃阻抗谐振器组成。为了进一步提高滤波器的选择性，在两个通带之间使用了一条激励线来产生另一个传输零点(TZ)。该双频带通滤波器工作频率分别为3.61 GHz和5.54 GHz，工作频带为3372 ~ 3883 MHz和5072 ~ 5889 MHz。该滤波器具有插入损耗低、体积小、带间隔离度高、选择性强等特点。

High Selectivity Dual-Band Bandpass Filter for 5G Mobile Communications

A high selectivity dual-band bandpass filter working at sub-6 GHz spectrum for 5G mobile communications is designed. It consists of two folded open-loop stepped-impedance resonators with four transmission zeros. To further improve the selectivity of the filter, a spur-line is employed to generate another transmission zero (TZ) between the two passbands. The proposed dual-band bandpass filter is operated at 3.61 GHz and 5.54 GHz, its working bands are 3372-3883 MHz and 5072-5889 MHz. The filter has a low insertion loss, compact size, high band-to-band isolation and high selectivity performance.
