ANTENNA FOR ELECTRONIC DEVICE

摘要

An electronic device includes a control module, a first antenna frame, and a second antenna frame. A first ground point, a first feed point, and a second ground point are respectively located on the first antenna frame. A second feed point, a third ground point, and a third feed point are respectively located on the second antenna frame. A switching unit and a low-pass circuit being electrically coupled between one end portion of the first antenna frame and one end portion of the second antenna frame, wherein the switching unit is controlled by the control module to selectively connect the first antenna frame and the second antenna frame. If the switching unit is closed, an antenna element formed between the first ground point and the third feed point is enabled, and the antenna element is operated to receive and/or transmit low frequency signal.
