Abstract
A coil pair having a transmission coil and a reception coil. The transmission coil is configured to transmit a transmission signal having a carrier. The reception coil is configured to receive from a source a reception signal having the carrier and data, and to significantly suppress the carrier while maintaining coupling with the source at any position along and any position proximate to the reception coil.

A coil arrangement, comprising:
- a single, concentrated, planar transmission coil configured to transmit a transmission signal having a carrier;
- and
- a planar reception coil configured to receive from a source a reception signal having the carrier and data, and to significantly suppress the carrier while maintaining coupling with the source at any position along and any position proximate to the reception coil,
- wherein at least a portion of the reception coil is located outside the transmission coil, and at least a portion of the reception coil is located inside the transmission coil.
A data transmission method comprising:
- transmitting by a single, concentrated, planar transmission coil a transmission signal having a carrier;
- receiving, by a planar reception coil, from a source a reception signal having the carrier and data;
- and
- significantly suppressing the carrier, by the configuration of the reception coil, while maintaining coupling with the source at any position along and any position proximate to the reception coil,
- wherein at least a portion of the reception coil is located outside the transmission coil, and at least a portion of the reception coil is located inside the transmission coil.
A planar reception coil, which is coupled with a single, concentrated, planar transmission coil, and is configured to receive from a source a reception signal having a carrier and data and to significantly suppress the carrier while maintaining coupling with the source at any position along and any position proximate to the reception coil, wherein the reception coil is separate from the transmission coil, wherein at least a portion of the reception coil is located outside the transmission coil, and at least a portion of the reception coil is located inside the transmission coil.
