论文摘要
本文提出了一个自包装的双带带通滤波器（DBBPF），具有高隔离和低插入损失（IL）的5G应用。为了获得高停止带抑制，产生了多个和可控的传输零（TZ）。这款新颖的DBBPF采用了一对四分之一波长的踩踏谐振器（QSIR）和半波长的发夹谐振器（HWHR）。该DBBPF对一对U形饲料线感到兴奋，该量U形饲料线在G6上设计以完全激发谐振器并同时引入源/负载TZ。在这封信中，将通过单独的电气和磁耦合路径（SEMCP）和混合EM耦合分析来讨论两个通带和TZ的产生。该DBBPF在中心频率的3.45 GHz和4.9 GHz的分数带宽（FBW）和6.9％的分数带宽（FBW）和6.9％的低IL中，分别用于5G应用。总尺寸为0.32λg*0.45λg。特别是在两个通带之间引入了三个可控的TZ。
A self-packaged dual-band bandpass filter (DBBPF) with high isolation and low insertion loss (IL) for 5G applications is proposed in this paper. To get high stopband suppression, multiple and controllable transmission zeros (TZs) are produced. This novel DBBPF is designed with a pair of quarter-wavelength stepped-impedance resonators (QSIRs) and a half-wavelength hairpin resonator (HWHR). This DBBPF is excited by a pair of U-shape feed lines, which are designed on G6 to fully excite the resonators and to introduce source/load TZs at the same time. In this letter, the generation of two passbands and TZs will be discussed by separate electric and magnetic coupling paths (SEMCP) and mixed EM coupling analysis. This DBBPF achieves a low IL of 0.85/1.15 dB with the fractional bandwidths (FBW) of 11.0% and 6.9% at the center frequencies of 3.45 GHz and 4.9 GHz for 5G application, respectively. The total size is 0.32λg*0.45λg. Especially, three controllable TZs are introduced between two passbands.
