1. An antenna device, comprising:
a circuit board which comprises:
a dielectric substrate which has a first face;
a first primary antenna and a first auxiliary antenna which operate at a first frequency range, are provided on the first face of the dielectric substrate respectively and are isolated from each other;
a second primary antenna and a second auxiliary antenna which operate at a second frequency range, are provided on the first face of the dielectric substrate respectively and are isolated from each other;
a third primary antenna and a third auxiliary antenna which operate at a third frequency range, are provided on the first face of the dielectric substrate respectively and are isolated from each other; and
a grounding unit comprising a first grounding face, a second grounding face and a third grounding face which are provided on the first face of the dielectric substrate and are isolated from each other, the first grounding face being positioned between the first primary antenna and the first auxiliary antenna to space the first primary antenna apart from the first auxiliary antenna, the first grounding face, the first primary antenna and the first auxiliary antenna cooperatively acting, and the first grounding face being positioned between the second primary antenna and the second auxiliary antenna to space the second primary antenna apart from the second auxiliary antenna, the first grounding face, the second primary antenna and the second auxiliary antenna cooperatively acting, the second grounding face being adjacent to the third primary antenna and the second grounding face and the third primary antenna cooperatively acting, the third grounding face being adjacent to the third auxiliary antenna and the third grounding face and the third auxiliary antenna cooperatively acting.
