Abstract:
The present application relates to an electronic device. The electronic device comprises a circuit board and an antenna apparatus, and the antenna apparatus is provided on one side of the circuit board. The antenna apparatus comprises a radiator and a feed point provided on the radiator. The circuit board is provided with a circuit area and a vacancy area; the circuit area is configured to arrange a circuit wiring, and the circuit area is provided with a feed end; the feed end is electrically connected to the feed point and is configured to feed excitation current to the radiator by means of the feed point; the excitation current forms a strong current area on the radiator, and the vacancy area and the strong current area are arranged opposite to each other. The circuit area surrounds at least a portion of the outer edge of the vacancy area, and the vacancy area is configured to cause current of the circuit area to flow to one side distant from the vacancy area. In the electronic device, since the circuit board is provided with the vacancy area, electric field distribution around the circuit board can be improved, SAR hot spots of the antenna apparatus are offset and dispersed, and an SAR value of the antenna apparatus can be reduced.
