摘　　要：随着无线通信技术的发展,具有短距离高速无线通信优势的超宽带(UWB)技术已成为现代无线通信领域研究的热点。由于超宽带系统频带与其他系统频带重叠而相互干扰,设计具有陷波特性的超宽带天线具有重要的意义。文章结合近年来超宽带天线研究的重难点,简要概括超宽带天线的技术背景,着重介绍带有陷波特性的超宽带天线,最后对超宽带天线的发展趋势进行了展望。With the development of the short-range and high-speed wireless communications, Ultra-WideBand（UWE） technology has become one of the most interesting research fields in modern wireless communication systems. To avoid the interference resulting from frequency o- verlap between the UWB system and other systems, the UWB antennas with band-notched char- acteristics become research hotspots in antenna field. With the research hotspots in recent years, a review of the technologies on UWB antennas was presented and technical background of UWB antennas explained. Then, various UWB antennas with characteristic of band-notched were ana- lyzed. Finally, possible progresses on UWB antennas in the future were pointed out and dis- cussed.
