Patent ID: 8061017

Claim:
A method of making a coil transducer system, comprising: forming a coil transducer comprising a generally planar substrate comprising opposing upper and lower surfaces and including therein a dielectric barrier, the dielectric barrier comprising an electrically insulating, non-metallic, non-semiconductor, low-dielectric-loss material, a first electrically conductive coil disposed above the upper surface of the substrate, the first coil extending between first and second coil input terminals disposed at opposite ends thereof; a second electrically conductive coil disposed below the lower surface of the substrate; the second coil extending between first and second output coil terminals disposed at opposite ends thereof; and providing a transmitter circuit comprising first and second transmitter output terminals; electrically connecting a first wire between the first transmitter output terminal and the first input coil terminal; electrically connecting a second wire between the second transmitter output terminal and the second input coil terminal; and configuring the first and second wires to be substantially parallel to one another, or to exhibit substantially similar angles respecting an azimuth extending along a major axis of the coil transducer, and have substantially a same first length such that the first and second wires are configured to minimize the pick-up of electromagnetic interference (“EMI”) thereby.
