Abstract
An antenna structure includes an antenna holder, a radiating body, a feed portion, and a grounding portion. The antenna holder includes a plurality of surfaces. The feed portion is positioned on one surface of the antenna holder and electronically connected to a first end of the radiating body. The ground portion is positioned on one surface of the antenna holder and electronically connected to a second end of the radiating body so as to form a loop antenna. An electronic element is surrounded by the loop antenna.
