Abstract

A novel 4-bands microstrip band pass filter (BPF) is proposed here, which consisted of two E-shaped microstrip Stepped-Impedance Resonators (SIR) with different sizes. Each of one E-shaped SIR is presented as a set of the dual pass band. Consequently, four pass bands are centered at 3.30 GHz, 4.83 GHz, 5.825GHz, and 8.65 GHz with the fractional bandwidth of 6.7%, 9.1%, 8.4%, and 8.2% can be obtained by the proposed design. The working frequency band can be changed by switching the two E-shaped SIRs. Due to its rich operation band resources, it can be used for 5G base station systems and other applications.

开关控制4波段带通滤波器与两个e形SIRs*

提出了一种新型的4波段微带带通滤波器(BPF)，该滤波器由两个不同尺寸的e型微带阶进阻抗谐振器(SIR)组成。每个e型SIR表示为一组双通带。因此，该设计可获得以3.30 GHz、4.83 GHz、5.825GHz和8.65 GHz为中心的4个通带，分数带宽分别为6.7%、9.1%、8.4%和8.2%。工作频带可以通过切换两个e型SIRs来改变。由于其丰富的运营频带资源，可用于5G基站系统和其他应用。
