Near-field wireless device including a first near-field antenna and a second near-field antenna
Abstract:
One example discloses a near-field wireless device, including: a stack of layers distributed along a first axis; a first near-field antenna having a conductive surface and embedded in a first layer within the stack of layers; wherein the conductive surface is configured to carry non-propagating quasi-static near-field electric-induction signals for on-body near-field communications; a second near-field antenna having an inductive loop and embedded in a second layer within the stack of layers; wherein the inductive loop is configured to carry non-propagating quasi-static near-field magnetic-induction signals for off-body near-field communications; wherein the first and second layers are different layers; and wherein the first and second antennas are not in galvanic contact.
