1. An antenna device comprising:
a radiating element;
a coupling circuit including a first coupling element and a second coupling element, the first coupling element being connected between the radiating element and a feeder circuit, the second coupling element being coupled to the first coupling element; and
a conductor portion connected to the second coupling element; wherein
the conductor portion is fed by the feeder circuit through the coupling circuit; and
a radiating property of the conductor portion is lower than a radiating property of the radiating element; and
the conductor portion is not directly connected to the radiating element.
