摘要
铁路线路进行养护时,养护现场可能出现恶劣的环境因素,造成养护设备操作人员和驾驶人员不能准确判定设备周围施工人员位置,从而造成人员碰撞安全隐患。针对上述问题,根据超宽带(UWB)实时定位技术,设计一种可适用于UWB定位技术的小型化超宽带微带天线,该天线的工作频段为3.04～11.3 GHz(S11<-10dB),覆盖整个超宽带天线规定的频段,在规定带宽内增益为3.9-6.3 dBi,且具有较好的全向特性。天线结构简单,易于制作。
When a railway line is being maintained, there may be harsh environmental factors at the maintenance site, which may cause equipment maintenance personnel and driver can not accurately determine the location of the construction personnel around the equipment, thus causing potential safety hazards. For this problem, the paper proposes a compact UWB real-time positioning microstrip antenna according to UWB real-time positioning technology. This antenna operates from 3.04 to 11.3 GHz, covering all the specifi ed working frequency bands of UWB, also presenting good omnidirectional radiation pattern and high gains throughout the UWB frequency range.
