ELECTRONIC DEVICE AND MULTI-BAND ANTENNA

摘要

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.
