Abstract
An antenna structure including a first radiator and a second radiator is provided. The first radiator includes a first section, a second section, and a third section. The first section has a feed-in end. The second section is adjacent to the first section and connected to a position of the first section close to the feed-in end. The third section is connected to the second section and the feed-in end to encircle a space. The second radiator is disposed around the first section and the second section. The second radiator includes a first end and a second end opposite to each other. The first end is a ground end. A coupling interval is formed between the second end and the third section. A first frequency band, a second frequency band, and a third frequency band are resonated by the first radiator and the second radiator.
