摘要

本文提出了一种新型的多传输极点双带带通滤波器，涉及4G和5G频段。它的电路结构由改进的耦合线结构和阶跃阻抗开路存根组成。给出了详细的分析案例。为了演示，模拟、制作和测量了工作在2.4 GHz和5 GHz、至少具有15db回波损耗和阻带抑制的设计原型。模拟结果与实测结果吻合较好。

Multi-transmission Poles Dual-band Bandpass Filter with Extended Bandwidth

In this paper, a novel dual-band bandpass filter with multiple transmission poles is proposed involving 4G and 5G bands. Its circuit configuration is composed of the modified coupled-line structures and step-impedance open-circuited stubs. The analyzed cases are provided in detail. For demonstration, a design prototype operating at 2.4 GHz and 5 GHz with 15-dB return loss and stopband rejection at least is simulated, fabricated, and measured. Good agreements between simulated and measured results are obtained.
