ABSTRACT:
The antenna device1contains a first radiating conductive plate3arranged above a grounding conductor2so as to be substantially parallel and opposite to the grounding conductor2; a second radiating conductive plate4adjacent to the first radiating conductive plate3with a slit5interposed therebetween; a feeding conductive plate6that extends orthogonally from an outer edge of the first radiating conductive plate3adjacent to the slit5, and a shorting conductive plate7that extends orthogonally from an outer edge of the second radiating conductive plate4adjacent to the slit5. A lower end of the feeding conductive plate6is connected to a feeding circuit, and a lower end of the shorting conductive plate7is connected to the grounding conductor2.
