摘要

本文提出了一种紧凑的单陷波带e型宽带带通滤波器。该带通滤波器的宽带响应是通过E型多模谐振器（MMR）得到的。通过嵌入SIR来抑制在通带范围内的无线电信号，得到一个单陷波带。该滤波器的分数带宽为119.4%。为了验证设计的有效性，将滤波器制作在介电常数εr为4.4，厚度t为1.6 mm的FR4上。通频带范围为2.43至9.63 GHz，陷波为5.86 GHz。所设计的带通滤波器的插入损耗为1.76 dB，回波损耗为10db。过滤器的紧凑尺寸为24毫米× 6.52毫米。

A Compact E Shaped MMR Wideband Bandpass Filter with Notched Band Utilizing SIR

This article presents a compact E-shaped wideband bandpass filter with a single notch band. The wideband response of proposed bandpass filter is obtained from E shaped multimode resonator (MMR). A single notched band is obtained by embedded a SIR to suppressed the radio signal fall in passband range. This filter demonstrates a fractional bandwidth of 119.4%. To verify the effectiveness of the design, the filter is fabricated on FR4 with a dielectric constant (ε_r) of 4.4 and a thickness(t) of 1.6 mm. The passband is from 2.43 to 9.63 GHz, with a notch at 5.86 GHz. The designed bandpass filter demonstrates an insertion loss of 1.76 dB and a return loss > 10 dB. The filter has a compact size of 24 mm× 6.52 mm.
