Patent ID: 10615502

Abstract:
One example discloses a near-field electromagnetic induction (NFEMI) antenna device, having: a coil, having first and second coupling points, configured to generate and/or receive a magnetic (H-field) near-field signal; a conductive structure having first and second coupling points separated by a distance; first and second feed points configured to carry a current from a transmitter and/or to a receiver circuit; wherein the first coupling point of the conductive structure is coupled to the first feed point and wherein the second coupling point of the conductive structure is coupled to the first coupling point of the coil; wherein the second coupling point of the coil is coupled to the second feed point; and wherein the conductive structure is configured to generate an electric (E-field) near-field in response to the current flowing over the distance between the first and second coupling points of the conductive structure.
