Abstract: An antenna structure includes a feeding layer, a resonation layer, and a ground layer. The feeding layer is configured for receiving an antenna feeding signal. The resonation layer is disposed at an area surrounding the feeding layer. A first predetermined distance is defined between the resonation layer and the feeding layer. The ground layer is disposed at a side of the feeding layer and the resonation layer. A second predetermined distance is defined between the ground layer and resonation layer. The ground layer includes a first support portion and a second support portion. The ground layer is not electrically connected to the feeding layer. The resonation layer is electrically connected to the first support portion and the second support portion of the ground layer.
