【摘要】 为推动北斗卫星导航系统在可穿戴领域的应用,解决传统硬质天线柔软性不足的问题,基于微带贴片天线设计经验公式,结合HFSS软件建模优化以及机织工艺,设计并制备织物微带贴片天线。通过理论计算与参数化仿真,优化贴片几何尺寸得到谐振频率为1.37 GHz的天线结构,其谐振点处回波损耗(S₁₁)为-25.45 dB,增益达5.45 dB,尺寸较优化前缩小了46.29%。结果表明:采用商业化导电纱与工业化剑杆织机,通过多层接结组织实现了天线辐射元与基板的一体化织造。织物纬密与谐振频率呈显著正相关（相关系数为0.982）,随着织物纬密的增大,谐振点向高频方向偏移且回波损耗减小。研究证实采用商业化导电材料与工业化织造工艺能够制备满足性能要求的柔性织物微带贴片天线。更多还原

【Abstract】 In order to promote the application of Beidou navigation satellite system in the wearable field and solve the problem of insufficient flexibility of traditional hard antennas, based on the empirical formula of microstrip patch antenna design, combined with HFSS software modeling optimization and weaving process, fabric microstrip patch antennas were designed and prepared.Through theoretical calculation and parametric simulation, an antenna structure with a resonant frequency of 1. 37 GHz was obtained by optimizing the patch geometric size. The return loss(S₁₁)at the resonant point was -25. 45 dB, the gain was 5. 45 dB, and the size was reduced by 46. 29% compared to pre-optimized version. The results showed that, using commercial conductive yarns and industrial rapier looms, the integrated weaving of antenna radiation elements and the substrate was realized through multi-layer junction structure. The weft density of the fabric had a significant positive correlation with the resonant frequency（ with a correlation coefficient of 0. 982）. As the weft density increased, the resonant point shifted towards higher frequencies and the return loss decreased. The research proves that flexible fabric microstrip patch antennas that meet performance requirements can be prepared by using commercial conductive materials and industrial weaving processes.更多还原
