Abstract:
A magnetic field probe comprising:a substrate; a flat conductive layer, provided on the substrate, having a coil, lead wires, and pads, the coil having at least one turn and outputting a signal indicative of a magnetic field enclosed by the coil, the lead wires extending from the coil to the pads, the signal from the coil being transmitted to the pads through the lead wires; an isolating layer of a dielectric material provided on the lead wires to protect the lead wires between the coil and the pads in the conductive layer; and a shielding layer of a conductive material provided on the isolating layer to protect the isolating layer, wherein the shielding layer prevents distortion of the magnetic field at the lead wires in conjunction with the isolating layer.
