  • Antenna structure
    Patent number: 11749891
    Abstract: An antenna structure includes a feeding radiation element, a first radiation element, a second radiation element, a shorting element, a first tuner, and a second tuner. The feeding radiation element has a feeding point. The first radiation element is coupled to the feeding radiation element. The first radiation element is coupled through the first tuner to a ground voltage. The feeding radiation element is coupled through the shorting element to the ground voltage. The second radiation element is adjacent to the first radiation element, and is separated from the first radiation element. The second radiation element is coupled through the second tuner to the ground voltage. The feeding radiation element is disposed between the first tuner and the shorting element.
