摘要:
目的：设计制作一种可用于脑出血检测的宽带微波天线。方法：在仿真软件中对天线结构和参数进行设计优化。利用人体头部电磁仿真模型进行脑出血检测仿真实验，检测14.1、33.5、65.4 mL 3种不同程度的脑出血。用实际制作的天线进行物理实验，分别测量水、95%酒精、植物油3种不同介电常数的液体在不同体积下（0~10 mL）的S11。结果：脑出血仿真实验中，在天线工作频带下（2.03~2.30 GHz，2.90~3.02 GHz）3种不同程度脑出血S11差异有统计学意义（P<0.05），表明该天线可以检测出不同程度脑出血。物理实验中，在实际制作天线工作频带下（2.00~2.27 GHz，2.85~2.90 GHz），3种液体的S11幅值有明显差异，在频谱的波谷位置差异最大，且液体体积越大，S11幅值的差异越大。提取2.17 GHz的数据观察，3种液体S11的幅值随着液体体积的变化而变化，且1~10 mL的S11幅值的差异有统计学意义（P<0.05），表明该天线可以检测物质介电常数和体积的变化。结论：该微波贴片天线有应用于脑出血检测的潜力。
Abstract:
Abstract: Objective To design and manufacture a wideband microwave antenna for intracranial hemorrhage detection. Methods The simulation software was used to optimize the antenna structure and parameters. The simulation experiment of intracranial hemorrhage detection was carried out using the electromagnetic simulation model of human head for detecting different amount of bleeding (14.1, 33.5 and 65.4 mL). The physical experiments were conducted with the actually manufactured antenna, and the S11 of 3 liquids with different dielectric constants, namely water, 95% alcohol and vegetable oil, were measured at different volumes (0-10 mL). Results In the simulation experiment of intracerebral hemorrhage, the S11 was statistically different in 3 different degrees of intracerebral hemorrhage at the working frequency bands of the antenna (2.03-2.30 GHz, 2.90-3.02 GHz) (P<0.05), indicating that the antenna could detect different degrees of intracerebral hemorrhage. In the physical experiment, at the working frequency band of the actual antenna (2.00-2.27 GHz, 2.85-2.90 GHz), the S11 amplitudes of 3 liquids differed significantly, and the largest difference occurred at the trough position of the spectrum, and the larger the liquid volume was, the greater the difference of S11 amplitude was. The observation on 2.17 GHz data showed that the S11 amplitudes of the 3 liquids changed with the liquid volume, and that there was significant difference in S11 amplitude at 1-10 mL (P<0.05), which demonstrated that the antenna could detect the changes in dielectric constant and volume of materials. Conclusion The microwave patch antenna has the potential for intracranial hemorrhage detection.
