  • Patent number: 12249772
    Abstract: An electronic device is provided. The electronic device includes a metal housing, a substrate and a radiating element. The metal housing is provided with a slot, and the slot includes an opening end and a closed end. The slot has a first wall of the slot and a second wall of the slot opposite to each other at the position of the opening end. The first wall of the slot is located between the second wall of the slot and the closed end. There is a predetermined distance between the first wall of the slot and the closed end. A feeding portion of the radiating element is connected to a feeding element and a signal is fed through the feeding element, so that the radiating element is used for exciting the metal housing to generate at least one resonance frequency.

  • Publication number: 20240145918
    Abstract: An antenna structure includes a metal mechanism element, a ground element, a feeding radiation element, a connection radiation element, a shorting radiation element, a parasitic radiation element, and a dielectric substrate. The metal mechanism element has a slot. The feeding radiation element has a feeding point. The connection radiation element is coupled to the feeding radiation element. The connection radiation element is further coupled through the shorting radiation element to the ground element. The parasitic radiation element is coupled to the ground element. The parasitic radiation element is disposed between the feeding radiation element and the shorting radiation element. The dielectric substrate is adjacent to the slot of the metal mechanism element. The feeding radiation element, the connection radiation element, the shorting radiation element, and the parasitic radiation element are all disposed on the dielectric substrate.
