Abstract
The antenna devicecontains a first radiating conductive platearranged above a grounding conductorso as to be substantially parallel and opposite to the grounding conductor; a second radiating conductive plateadjacent to the first radiating conductive platewith a slitinterposed therebetween; a feeding conductive platethat extends orthogonally from an outer edge of the first radiating conductive plateadjacent to the slit, and a shorting conductive platethat extends orthogonally from an outer edge of the second radiating conductive plateadjacent to the slit. A lower end of the feeding conductive plateis connected to a feeding circuit, and a lower end of the shorting conductive plateis connected to the grounding conductor
