Abstract
A dual-frequency antenna structure includes a substrate, and a grounding element, a conductive sheet, a transmitting antenna, and a receiving antenna that are disposed on the substrate. The transmitting antenna includes a first coupling conductive pad, a first conductive column that is electrically coupled to the first coupling conductive pad and the conductive sheet, and a first feeding conductive pad. The first feeding conductive pad can produce a capacitive effect with each of the first coupling conductive pad and the grounding element. The receiving antenna includes a second coupling conductive pad, a second conductive column that is electrically coupled to the second coupling conductive pad and the conductive sheet, and a second feeding conductive pad. The second feeding conductive pad can produce a capacitive effect with each of the second coupling conductive pad and the grounding element.
