摘　　要：针对传统杆状天线在现代化战争应用场景中存在的带宽窄、质地硬以及隐蔽性与便携性较差等问题,提出了一种基于柔性介质材料的可穿戴式天线,该天线采用平面单极子天线的形式,极大地降低天线的剖面。借助电磁仿真软件CST Studio Suite 2023进行仿真分析,该天线尺寸为270 mm×270 mm×1.1 mm,重量仅有120 g,包含0.37~1.8 GHz的实测宽带频段,在人体加载影响下,实测频段范围超过0.3~1.8 GHz。给出了反射系数S_(11)、辐射方向图的结果,分析了人体对天线的影响,结合通信电台开展实物对比测试。仿真与实测表明,可穿戴式天线在士兵手持电台中具有一定的应用前景。In consideration of the problems such as narrow bandwidth,hard texture and poor concealment and portability of traditional rod antenna applied in modern war,a wearable antenna based on flexible dielectric material is proposed,which takes the form of planar monopole antenna and greatly reduces the antenna profile.The electromagnetic simulation software CST Studio Suite 2023 is used for simulation analysis.The size of the antenna is 270 mm×270 mm×1.1 mm,and its weight is only 120 g,including a measured broadband frequency band from 0.37 GHz to 1.8 GHz,and the measured frequency bands range from 0.3 GHz to 1.8 GHz under the influence of human loading.The results of reflection coefficient S_(11)and radiation pattern are given,and the influence of human body on antenna is analyzed.Comparison test based on actual communication station is performed as well,and the results show the wearable antenna has a certain application prospect in individual handheld radio station.
