  • Patent number: 11088727
    Abstract: An electronic device includes a middle frame. The middle frame includes a slit, a first strip groove and a second strip groove, and the slit extends inward from an edge of the middle frame so as to be communicated to the first strip groove and the second strip groove; and a first grounding point, a second grounding point, a data signal feed point, a frequency modulation circuit and an NFC feed point. The data signal feed point, the frequency modulation circuit and the NFC feed point as well as the first grounding point are positioned on a same side of the slit, the data signal feed point, the frequency modulation circuit and the first grounding point cooperatively radiate 2G, 3G or 4G communication signals, the data signal feed point, the NFC feed point, the middle frame, the slit and the second grounding point cooperatively radiate 5G communication signals, and the NFC feed point and the first grounding point cooperatively radiate NFC signals.
