| 摘 要： | 平面电感实现了电感器件的小型化和片式化.当工作频率达到射频或微波段时,应考虑平面电感线圈的辐射和散射对其周围电路的影响.本文采用小波矩量法研究了PCB(printed circuit board)平面螺旋电感的电磁辐射特性.采用区间小波作为矩量法中的基函数和检验函数,计算了电感中的电流分布,给出了辐射方向图.与传统矩量法相比,小波矩量法可以使系数矩阵稀疏化,从而节省了计算机资源和计算时间.

| Abstract: | Planar inductors downsize the inductor devices.The effect of radiation and scattering from the windings must be considered when the signal frequency reaches to radio or microwave bands.Electromagnetic radiation from PCB planar inductors is studied by wavelet method of moment.The current distribution in PCB inductors is evaluated by using Coifman intervallic scarlet as the base function and test function in the Mom.The radiation patterns of two circular PCB planar inductors are given finally.The coefficient ... |
