摘　　要：通过将平面螺旋电感器中的单股宽导线分成并联的多条细导线而在电感中形成多电流路径结构,可以降低电感的高频损耗并提高其品质因数(Q值)。利用HFSS电磁仿真软件对具有多电流路径结构的螺旋电感进行了设计与优化。结果表明,在尺寸不变的情况下,采用了多电流路径结构的平面螺旋电感的Q值提高了80%以上,这为高Q值小型平面螺旋电感的研制提供了思路。Employing the multi-current path structure in planar spiral inductor,by dividing the single wide track into multiple parallel connected trickle tracks,could reduce the frequency loss and increase the quality factor of the inductor.The planar spiral inductor with multi-current path structure was designed and optimized by using the HFSS software.The results show that,with no change in inductor size,the quality factor of planar spiral inductor is increased by above 80% with the employment of multi-current path structure.This provides some valuable insights into the design of small size high Q value planar spiral inductor.
