分析超宽带(UWB)无线通信技术特点,进而探讨UWB射频滤波器在该系统中的作用.采用半波长耦合微带线接联的方法及发夹型结构对UWB滤波器进行设计,并分析其特性,实验结果与计算机仿真基本一致,可为UWB带通滤波器的分析和设计提供进一步研究的依据.
According to the characteristics of UWB wireless communication,the UWB band-pass filters are designed by using the parallel-coupled microstrip and the Hairpin-line means.Filter response is characterized by measuring its transmission and reflection coefficients.The measured results are in good agreement with the simulated results.It provide the basis for the analysis and the design of the UWB band-pass filter in the future.
