Abstract
A capacitive antenna structure comprises a substrate and a sheet-shaped capacitor. The substrate has a radiating metal layer and a grounding metal layer thereon. The radiating metal layer has a first groove to expose the front surface of the substrate, the first groove having a signal feeding hole therein and having a second groove on the edge. The grounding metal layer has a third groove on the edge to expose the substrate, the third groove being opposite to the second groove, the third groove having a first contact and a second contact on two sides respectively to electrically connect to the capacitor. The third groove may connect to a fourth groove to expose the substrate, the fourth groove having a signal transmission line therein, and the signal transmission line having the signal feeding hole to connect a cable.
