新型正六边形微带多模带通滤波器

内容简介：提出了新型贴片缺陷结构的六边形谐振器，并对该结构及其谐振特性进行了研究和分析。利用分形技术设置贴片缺陷，充分激励起六边形谐振器的前三个模式工作，设计实现了三通带滤波器，并且使滤波器的性能得到了较大改善。对设计的滤波器进行了加工测试，实验结果与仿真结果吻合。这种新型滤波器具有插入损耗低、频率选择性好、易加工以及小型化等优点。

Abstract：New defected hexagonal patch resonator is proposed, and its resonant performance is studied and analyzed. Fractal technique is introduced to generate patch defection which inspire the first three modes of hexagonal resonator operate together, and new tri-band bandpass filter is realized. It shows with the assistance of fractal, filter performance is greatly improved. The new filter is fabricated and tested, and the measurement is agreement with the simulation. The new filter has advantages of low passband insertion loss, good frequency selectivity, easy fabrication and miniaturization, et al.
