Abstract This article presents a design of highpass filter (HPF) for millimeter-wave (mm-wave) applications using a square complementary split-ring resonator (SCSRR). A miniaturized size HPF filter is obtained by overlapping the Right-Hand (RH) and Left-Hand material. The arrangement of inter-digital parallel coupled capacitor and SCSRR offers low insertion loss, high selectivity with a sharp roll-off factor over a wide bandwidth of 15.9 GHz (from 34.1 to 50 GHz). Generally, SCSRR offers narrow passband/stopband however this prototype has a passband over a wide range of frequency. The proposed HPF has an appreciable agreement between simulated and fabricated results. Further, the filter is realized in the equivalent circuit model and their electrical elements functions are also discussed. This prototype has a cut-off frequency (fc) of 34.1 GHz with a maximum passband insertion loss of 1.45 dB. The fabricated area of the filter is 0.16λg × 0.09λg × λg and where λg is the guided wavelength at cutoff frequency fc.

使用互补裂环谐振器设计用于 5G 毫米波应用的紧凑型高通滤波器

摘要 本文介绍了一种用于毫米波 (mm-wave) 应用的高通滤波器 (HPF) 设计，该设计使用方形互补裂环谐振器 (SCSRR)。通过重叠右手 (RH) 和左手材料获得小型化的 HPF 过滤器。叉指并联耦合电容器和 CSRR 的排列提供了低插入损耗、高选择性以及在 15.9 GHz（从 34.1 到 50 GHz）的宽带宽内的急剧滚降因子。通常，CSRR 提供窄通带/阻带，但是该原型在很宽的频率范围内具有通带。提议的 HPF 在模拟结果和制造结果之间具有明显的一致性。此外，滤波器是在等效电路模型中实现的，还讨论了它们的电气元件功能。该原型的截止频率 (fc) 为 34。1 GHz，最大通带插入损耗为 1.45 dB。滤波器的制造面积为 0.16λg × 0.09λg × λg，其中 λg 是截止频率 fc 处的引导波长。
