This paper proposes the optimum placement of an LF antenna in a small mobile device to minimize coverage range degradation of a PASE system. The small mobile device, vehicle, and 3-axis LF antenna are modeled as piecewise triangular meshes and simulated using a full-wave electromagnetic simulator to verify the feasibility of mounting the LF antenna in a small device. We then find the optimum placement of the 3-axis LF antenna inside the mobile device to maximize the coverage range of the system. Finally, the received power of the 3-axis LF antenna is analyzed in conjunction with the PASE system for vehicle application to accurately estimate the system performance. The results demonstrate that the position optimization of the LF antenna in the small mobile device is capable of maximizing the coverage range of the PASE system.

车载应用小型移动设备中3轴LF天线的最佳放置

本文提出了在小型移动设备中最佳放置LF天线的方法，以最大程度地减小PASE系统的覆盖范围降低。将小型移动设备，车辆和3轴LF天线建模为分段三角形网格，并使用全波电磁模拟器进行仿真，以验证将LF天线安装在小型设备中的可行性。然后，我们找到在移动设备内部放置3轴LF天线的最佳位置，以最大化系统的覆盖范围。最后，结合用于汽车应用的PASE系统分析了3轴LF天线的接收功率，以准确估算系统性能。结果表明，小型移动设备中LF天线的位置优化能够最大化PASE系统的覆盖范围。
