  • Patent number: 11023056
    Abstract: An antenna structure applied in a stylus includes a first radiating portion, a second radiating portion, and a main body. The second radiating portion corresponds to the first radiating portion. The main body covers the first radiating portion and the second radiating portion. The first radiating portion electrically connects to a feed source to feed in current, the first radiating conducts the current to activate a first mode to generate radiating signals, the main body couples the current from the first radiation portion, the second radiating portion couples the current from the main body, the first radiating portion, the main body, and the second radiating portion conduct the current and connect to ground to activate a second mode to generate radiation signals. A stylus using the antenna structure is also provided.
