双模微带三角形贴片滤波器的改进设计

双模微带谐振器用于微波滤波器设计时具有独特的优点。近年来出现了一些由双模微带三角形贴片谐振器设计的滤波器,这类滤波器结构简单、尺寸小、通带损耗小、功率容限大。在传统的双模微带三角形带通滤波器的基础上,利用分形结构提出一种新型的双模微带三角形带通滤波器,并对此结构的性能进行了分析和研究。实验和测量结果表明,改进后的滤波器在保持原有滤波器性能的基础上,由于引入了分形结构使滤波器的尺寸更加紧凑、有更好的带外抑制能力。仿真和实测结果基本吻合。

Improvement Design of Dual-Mode Microstrip Triangular Patch Filter

Dual-mode microstrip resonators have particularmerits in the design of microwave filters.In recent years,dual-mode microstrip triangular patch resonators have been applied in filter design.These filters own merits such as simple and compact structures,low insertion loss and higher capability of power handling.This paper proposes a novel dual-mode microstrip triangular patch filter by using fractal structure based on the traditional filters.Test and measurement results indicate that the performance of the ne...
