摘要

针对现有陷波超宽带天线的陷波带宽难以控制的问题,提出一种陷波带宽可控的缝隙超宽带天线.首先采用宽矩形缝隙天线辐射产生超宽带特性,使其带宽能覆盖3.1～10.6GHz频段;然后在地板嵌入一对倒L形槽来实现陷波特性,陷波带宽可以通过调整L形槽的宽度或位置来控制;最后设计并加工了一副在5.0～6.0GHz频段内具有阻带特性的超宽带天线,有效地阻隔了无线局域网系统对超宽带系统的影响.

Abstract

As the notched bandwidth of the existing band-notched ultra-wideband（UWB） antennas are difficult to control,this paper presents a novel kind of UWB slot antenna with controllable notched bandwidth.In the investigation,first,a broadened rectangular solt antenna is used to generate ultra-wideband characteristics covering 3.1～10.6GHz band.Then,a pair of inverted L-shaped slits is embedded in the ground to create a band-notched function.The notched bandwidth can be easily controlled by adjusting the width and location of the slits.Finally,an UWB antenna with rejection band at 5.0～6.0GHz is successfully designed and fabricated,which effectively eliminates the potential interference from WLAN.

Key words： ultra-wideband antenna; notched characteristic; slot antenna; L-shaped slit; controllable notched bandwidth
