Abstract
The present invention comprises an antenna system consisting of two generally co-axial near field antennas, one mounted around the circumference of a human head, the other mounted on the body. The preferred embodiment discloses the dimensions necessary to create a viable near field communications (NFC) channel with existing commercial off-the-shelf (COTS) NFC circuits to create a secure wireless link between the head and shoulders.
Claims2
An antenna system, the system comprising:
- a first antenna coil affixed around the circumference of a person's head so that the plane formed by the antenna coil is generally parallel to the ground when the person is standing in the anatomical position;
- and
- a second antenna coil that is inductively coupled to the first antenna coil and affixed to the person's body at or below the shoulders and parallel to the first antenna coil,
- wherein the antenna coils are configured to intercommunicate using an NFC protocol and to operate at frequencies between 12.56 MHz and 14.56 MHz.
