Abstract (en)
A device having a quadrature near field communication antenna is provided. The device comprises: a housing; a first NFC (near field communication) antenna comprising a coil about parallel to a given side of the housing enabled 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 enabled to produce a second magnetic field perpendicular to the first magnetic field; and, a circuit for operating the first NFC antenna and the second NFC antenna in quadrature phase.
