摘要: 设计一种共面波导馈电的2.45 GHz柔性微带天线, 通过在高频结构仿真(HFSS)软件中构建3层人体组织模型(皮肤脂肪肌肉), 仿真分析人体组织对天线关键参数的影响, 优化柔性天线的结构参数, 并研究柔性微带天线在弯曲状态下的传感性能. 测试结果表明: 天线中心频率在2.40 GHz处的回波损耗为-26 dB, 工作频带为2 030~2 770 MHz; 天线弯曲时中心频率发生偏移, 可应用于测量弯曲状态下的不同曲率半径.

Abstract: We designed a coplanar waveguidefed 2.45 GHz flexible microstrip antenna. The threelayer human tissue model (skinfatmuscle) was constructed in the high frequency structure simulator (HFSS) software, the influence of human tissue on the key parameters of the antenna was analyzed, the structural parameters of the flexible antenna were optimized, and the sensing performance of the flexible microstrip antenna under bending condition was studied. The test results show that the return loss of the antenna is -26 dB at 2.40 GHz and the frequency band is 2 030—2 770 MHz. When the antenna is bent, the centre frequency is offset, which can be used to meature different radius of curvature in the bending state.
