Abstract: An electronic device with multi-band antenna includes a first antenna frame, a second antenna frame, and a switching unit being electrically coupled between the first antenna frame and the second antenna frame. A first feed point only is located on the first antenna frame and multiple electrical connection points, a second feed point, and a ground point are located on the second antenna frame. One end of the first antenna frame can be connected to one of the electrical connection points by controlling the switching unit, and multiple radiating elements, able to radiate signals in different frequency bands, are formed on the multi-band antenna. Radiating elements are formed between the first feed point and the second feed point and the ground point.

Abstract: 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.

Abstract: An electronic device has a multi-band antenna which includes an antenna frame and multiple feed points and multiple ground points located on the antenna frame. The multiple feed points include a first feed point located at one end portion of the antenna frame and a second feed point located between two end portions of the antenna frame. The multiple ground points include a first ground point located between the two end portions of the antenna frame and a second ground point located at the other end portion of the antenna frame. The multiple feed points and the multiple ground points are alternately located on the antenna frame, and multiple radiating elements are formed on the antenna frame and are configured to radiate signals having different frequency bands. Each radiating element is formed between a feed point and a ground point.
