Abstract: An antenna system includes an antenna body, a tunable component, and at least one of a first filter and a second filter. The antenna body is connected to the tunable component. The first filter is connected in parallel to the tunable component, and the first filter presents a high impedance characteristic in a low frequency band, and presents a low impedance characteristic in a high frequency band. The second filter is connected in series between the antenna body and the tunable component, a first end of the second filter is connected to the antenna body, and a second end of the second filter is connected to the tunable component. The second filter presents a low impedance characteristic in a low frequency band, and presents a high impedance characteristic in a high frequency band.
