摘要
随着对超宽带平面天线的研究和广泛应用,在超宽带天线中实现对其他无线通信设备特别是WLAN设备的干扰抑制成为近年来的研究热点。介绍了陷波特性超宽带天线的技术背景,对近几年国内外关于陷波超宽带天线的最新研究成果进行了分析总结,研究成果对超宽带天线的设计和频带的抑制具有一定的指导作用。最后对无线通信中超宽带天线的发展趋势进行了展望。
With the research artd wide applications of ultra-wideband planar antenna in recent years, it is an attractive topic how to reject electromagnetic interference on nearby frequency communication systems such as Wireless LAN （WLAN） caused by ultra-wideband planar antenna. Technical back-ground of band-notched UWB antennas is described first, recent development of UWB antennas is summarized, a direction is provided for designing and band rejected of ultra-wideband planar antenna in the consequences. Finally, possible progresses on band-notched UWB antennas in the future arepointed out and discussed.
