Abstract:
1. A device comprising: a housing; a first NFC (near field communication) antenna comprising a coil about parallel to a given side of the housing configured to produce a first magnetic field that extends from the given side of the housing; a second NFC antenna about parallel with the first NFC antenna, the second NFC antenna comprising at least one respective coil forming two opposing current loops configured to produce a second magnetic field perpendicular to the first magnetic field; a third NFC antenna about parallel with the first NFC antenna and the second NFC antenna, the third NFC antenna comprising at least two further coils configured to produce a third magnetic field extending from the housing, perpendicular to the first magnetic field and the second magnetic field; and, a circuit for operating the first NFC antenna and the second NFC antenna in quadrature phase.
