  • Publication number: 20240145902
    Abstract: A Wi-Fi and Bluetooth combined antenna apparatus and a configuration method therefor, and a terminal device. The Wi-Fi and Bluetooth combined antenna apparatus includes a Wi-Fi antenna, a ground plate, a perturbation unit, and a Bluetooth antenna. The Wi-Fi antenna generates a ground plate current on the ground plate; the perturbation unit is configured to generate a reverse current after being excited by the ground plate current, and a current zero point area is formed on the ground plate after the reverse current is superimposed with the ground plate current; and the Bluetooth antenna is disposed at a position of an edge of the ground plate corresponding to the current zero point area. In this way, isolation between the Bluetooth antenna and the Wi-Fi antenna is better improved.
