  • Patent number: 11437709
    Abstract: The present disclosure provides an electronic device with advanced antenna. The electronic device includes: a display screen; a metal frame surrounding a side edge of the display screen; and a connecting component disposed between the side edge of the display screen and a top end of the metal frame; wherein a height of the connecting component is larger than a preset height such that a portion of the side edge of the display screen not facing the metal frame has at least the preset height. Since the height of the connecting component is larger than the preset height such that the area of the portion of the side edge of the display screen which faces directly the metal frame may be smaller than a predetermined value. Thus, interruption between the display screen and the metal frame may be reduced or eliminated.
