摘　　要：随着无线通信需求的不断增加,双频便携式电话和无线局域网被广泛应用,双带滤波器也成为这些通信系统前端的重要器件,其具有小型化、低功耗、高选择性等特点,非常适合应用于现代通信系统。该文主要研究微波双带带通滤波器的设计理论和研究方法,介绍近几年微波双带带通滤波器的研究与进展,并从电路结构特征及设计方法上对其进行了分类讨论,最后简要报道我们在双带带通滤波器领域的研究工作以及微波双频带滤波器的研究态势与未来的展望。In recent years, dual-band portable telephones and WLAN（wireless local area networks） become quite popular due to the need of wireless mobile communications. Dual-band filters become key components in the front of these conmunications systems due to its characteristics of miniaturization, low loss and good selection. This paper gives a study on the design technique and theory of dual-band filters and introduces the development of the dual-band microstrip filter in recent years. Based on the circuit structure and design method, the dual-band filters are classified and discussed. Finally,our work in this field and the prospect of dual-band filter is briefly reported.
