The manuscript presents a broadside coupled ultra-wideband (UWB) bandpass filter with quasi-elliptic response having multiple transmission zeros (TZs) in/out of the UWB spectrum. Developed on a low cost substrate (FR4), the basic geometry consists of a short-circuited co-planar waveguide (CPW) in ground coupled to the back-to-back arranged microstrip lines on the top. This broadband balun architecture leads to a 3rd order bandpass filter (BPF) with good quasi-elliptic frequency characteristics. Later, split ring resonators (SRRs) and folded SRRs (FSRRs) are placed adjacent to the input/output (I/O) feeding lines to develop the multiple in/out band TZs. The proposed structure is fabricated and measured for its frequency characteristics. The notched-BPF occupies an area of 21.6 × 16 mm2.

基于微带到CPW转换的多缺口UWB-BPF设计与分析

该手稿提出了一种宽边耦合超宽带 (UWB) 带通滤波器,它具有准椭圆响应,在 UWB 频谱内外具有多个传输零点 (TZ)。在低成本基板 (FR4) 上开发,基本几何结构包括接地的短路共面波导 (CPW),与顶部背靠背排列的微带线耦合。这种宽带巴伦架构导致具有良好准椭圆频率特性的三阶带通滤波器 (BPF)。后来,裂环谐振器 (SRR) 和折叠 SRR (FSRR) 被放置在输入/输出 (I/O) 馈线附近,以开发多个输入/输出带 TZ。所提出的结构被制造并测量其频率特性。缺口 BPF 占据 21.6 × 16 mm 的面积2.
