摘　　要：根据煤矿井下对可穿戴天线的要求,在半模衬底集成空腔天线的基础上,采用折叠结构降低天线主体的宽度,并利用水平放置的馈电探针实现可穿戴天线扁平化,设计了一种矿用可穿戴翻折结构半模衬底集成空腔天线。仿真结果表明,该天线在5GHz处于谐振状态,-10dB带宽约为254 MHz,最大增益为5.4dBi,辐射效率为70%,辐射方向具有较宽的主瓣和较低的背向辐射,且可通过增加上层衬底厚度来增加天线-10dB带宽。Based on half-mode substrate-integrated cavity antenna,a mine-used wearable folded halfmode substrate-integrated cavity antenna was designed considering requirements for underground wearable antenna.Width of antenna is reduced by use of folded geometry,and planar antenna is realized with horizontal feeding probe structure.The simulation results show that the antenna resonates at 5 GHz,-10 dB bandwidth is 254 MHz,the maximum gain is 5.4dBi,radiation efficiency is 70%,and the antenna has radiation direction with wide beamwidth and low back radiation.Besides,-10 dB bandwidth of the antenna can be increased with thicker upper substrate.
