Abstract

The present invention relates to a loop antenna with a capacitive structure, comprising a grounding surface, a dielectric substrate, a signal feeding metal contact, and a radiation metal wire, wherein the radiation metal wire comprises a first radiation metal sub-wire, a second radiation metal sub-wire and a capacitive coupling metal wire. The first radiation metal sub-wire has a starting terminal and an ending terminal, and the starting terminal is connected to the signal feeding contact. The second radiation metal sub-wire has a starting terminal and an end terminal, and the ending terminal is connected to the grounding surface. The capacitive coupling metal wire has a starting terminal and an ending terminal, which are connected to the ending terminal of the first radiation metal sub-wire and the starting terminal of the second radiation metal sub-wire respectively. The capacitive coupling metal wire is located close to and parallel to the grounding surface to generate capacitive coupling, causing reduction of the size of the antenna. The present invention is employable to systems of digital TV band.
