摘要
本文提出了一个工作在12.5GHz的带通滤波器,通过微带线结构实现高品质的交叉耦合谐振腔,并给出了HFSS仿真结果。该滤波器尺寸小且结构简单紧凑,通带陡度较高。
In this paper, a bandpass filter using microstrip line is proposed. The center frequency of 12.5GHz is achieved by high-quality crossing-coupled resonant cavity, and the HFSS simulation results are given in this paper. The filter has small size, simple and compact structure and high bandpass steepness.
