Abstract:
One example discloses a near-field electromagnetic induction (NFEMI) antenna, having: a core; an electric antenna including an electrically conductive surface; a magnetic antenna including a first coil coupled to a second coil; a first feeding connection coupled to one end of the first coil; a second feeding connection coupled to another end of the first coil and coupled to one end of the second coil; wherein the first and second feeding connections are configured to be coupled to an electrical apparatus; wherein another end of the second coil is coupled to the electrically conductive surface; a magnetic permeable material between a first side of the magnetic antenna and the core; and wherein the first coil, the second coil, the magnetic permeable material, and the electrically conductive surface are wrapped around the core.
