| Abstract: | 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. |
