摘要
该文提出了一种基于纺织材料的可穿戴双频天线结构。天线采用和微带天线一样的原理,馈电方式选择微带线馈电。天线远端控制低频,近段控制高频,天线介质材料采用普通毛毡布,辐射贴片采用黄铜箔,天线在2.45GHz和5.8GHz的民用ISM频段S11分别为-21d B和-30d B。采用HFSS仿真软件,建立模型对双频天线在平放和弯曲条件下进行了仿真,仿真数据表明:该天线在自由空间中沿X、Y轴弯曲时谐振频率、带宽、增益方向图变化较小;天线靠近人体表皮附近时,整体性能有一定降低,但仍满足穿戴系统中无线通信系统的要求。
In this paper,a wearable dual frequency antenna structure based on textile materials is proposed.The antenna is the same as the microstrip antenna,and the feed mode is fed by the microstrip line.The remote control of the antenna is controlled by low frequency,the near section is controlled by high frequency,the antenna material is made of ordinary felt,the radiation patch is made of brass foil,and the antenna at 2.45GHz and 5.8GHz's civilian ISM band S11 are-21dB and-30dB respectively.By using HFSS simulation software,establish the model of dual frequency antenna in the flat and bending condition is simulated.The simulation data shows that the antenna in free space along X,Y axis bending resonant frequency,bandwidth,gain pattern of small changes;near the antenna close to human skin,the overall performance is reduced,but can meet the wireless comimuncation system for wearable system requirements.
