An electronic device is provided. The electronic device includes a metal housing, a first opening, a first metal line, a first grounding point and a first current zero point. The first opening passes through the metal housing. The first metal line is disposed inside the first opening, wherein a first end of the first metal line is electrically connected to a side of the first opening, and a second end of the first metal line has a first feeding point. The first grounding point and the first current zero point are located on the side of the first opening. The metal housing forms a first loop antenna to transmit or receive a first radio frequency signal by a first excitation path from the first feeding point to the first grounding point. |
