  • ANTENNA APPARATUS AND ELECTRONIC DEVICE
    Publication number: 20260051653
    Abstract: An antenna apparatus and an electronic device. A relay coil is added near a main coil of the antenna apparatus, and a corresponding matching circuit is designed for the relay coil, to control a current direction of the relay coil to be the same as/opposite to a current direction of the main coil, so that magnetic fields generated by the main coil and the relay coil are superposed at a peer coil to achieve an effect of magnetic field enhancement. In addition, when the antenna apparatus is applied to an electronic device, if there is a metal assembly near the antenna apparatus in the electronic device, a current direction of the relay coil is the same as/opposite to a current direction of the main coil by designing a corresponding matching circuit, thereby improving performance of the antenna apparatus.
