【摘要】 超宽带(Ultra-wide band,UWB)天线作为超带宽通信系统的核心部件,直接决定整个系统的通信效能。因超宽带天线小巧精简的结构、更低的功耗、多样灵活集成方式使其应用极为普遍。但无线局域网(WLAN)窄带系统的干扰一直没有很好的解决,针对此问题,设计了具有带阻功能的超宽带天线,并进行了仿真和实验测试。测试结果表明,当天线电压驻波比小于2时,工作频带为3.1～5.16GHz和5.9～15GHz;当电压驻波比大于2时,天线的阻带频段为5.16～5.9GHz,能很好地抑制WLAN系统的干扰。更多还原

【Abstract】 The communication performance of the system is determined by the ultra-wideband(UWB)antenna which is the core component of the UWB communication system.The UWB antennas are widely used in communication systems,as it has the advantages such as low profile,low power consumption and flexible integration.However,the interference of wireless local area network(WLAN)narrowband system has not been solved very well.To solve this problem,an UWB antenna with band-notched function is designed and simulated.The simulation and experiment results show that the operating frequency band is from 3.1 to 5.16 GHz and from 5.9 to 15 GHz,when the antenna voltage standing wave ratio is less than 2.When the voltage standing wave ratio is greater than 2,the band elimination band of the antenna is from 5.16 to 5.9 GHz,which can suppress well the interference of the WLAN system.更多还原
