Abstract

A wide-band microstrip bandpass filter (BPF) based on the improved composite right/left-handed transmission line (CRLH-TL) structure is presented in this paper. Compared to the traditional CRLH-TL with via hole, the improved one is an all-planar structure, which owns the advantage of fabrication and loss. The equivalent lossless LC circuit model of the proposed structure is established. EM software Sonnet is adopted to design the wide-band filter with bandwidth of 1.4 GHz (from 1.9 GHz to 3.3 GHz). The circuit occupies only 20.6 × 12.8 mm2. Finally, the fabrication and measurement are implemented. A good agreement between simulation and measured results verifies the validity of the design methodology.

基于复合左右传输线结构的宽带带通滤波器设计

提出了一种基于改进型左右复合传输线结构的宽带微带带通滤波器(BPF)。与传统的通孔CRLH-TL相比，改进后的CRLH-TL是全平面结构，具有制造和损耗方面的优势。建立了该结构的等效无损LC电路模型。采用EM软件Sonnet设计带宽为1.4 GHz (1.9 GHz ~ 3.3 GHz)的宽带滤波器。电路面积仅为20.6 × 12.8 mm2。最后，进行了制作和测量。仿真结果与实测结果吻合较好，验证了设计方法的有效性。
