摘　　要：介绍了一种新型的基于印刷电路板技术基础上制造的环形微型磁通门传感器的工作原理和结构。这种传感器由三层组成,上下两层用来制作铜板线圈,中间层用来制作25μm厚的高磁导率无定形铁磁薄芯。文中还研究了该传感器在不同的外部磁场方向下环形磁通门传感器输出电压和和磁感的函数关系。The paper mainly discusses the working principle and structure of a new toroidal micro-magnetic fluxgate integrated inside printed circuit boards （PCB）. The fluxgate sensor are built up of three layers of which the outer layers carry the Cu winding coil patterns and the inner layer is a patterned high permeability ferromagnetic sheet core with a thickness of 25 um. The output voltage of the fluxgate sensor has been studied as a function of the magnetic field in different orientation of the external field.
