12. An antenna device, comprising:
a circuit board which comprises:
an insulating carrier having a first face and a second face which are opposite to each other;
a first primary antenna which operates at a first frequency segment and having a first feeding-in section, the first primary antenna being provided on the first face of the insulating carrier, the first primary antenna comprises a first monopole antenna connected with the first feeding-in section;
a first auxiliary antenna which operates at the first frequency segment and having a second feeding-in section and a second grounding section adjacent to the second feeding-in section, the first auxiliary antenna being provided on the first face of the insulating carrier, the first auxiliary antenna comprises a second monopole antenna which is connected with the second feeding-in section and at least one coupling element which extends outwardly from the second grounding section and is spaced apart from and adjacent to the second monopole antenna so as to be electrically coupled with the second monopole antenna;
a second primary antenna which operates at a second frequency segment and having a third feeding-in section, the second primary antenna being provided on the first face of the insulating carrier, the second primary antenna comprises an inversed-F antenna connected with the third feeding-in section;
a second auxiliary antenna which operates at the second frequency segment and having a fourth feeding-in section, the second auxiliary antenna being provided on the first face of the insulating carrier, the second auxiliary antenna comprises a third monopole antenna connected with the fourth feeding-in section; and
a grounding unit comprising a first grounding face provided on the first face of the insulating carrier, the first grounding face is provided with a first grounding section adjacent to the first feeding-in section, a third grounding section adjacent to the third feeding-in section and a fourth grounding section adjacent to the fourth feeding-in section such that first grounding face is positioned between the first primary antenna and the first auxiliary antenna and is positioned between the second primary antenna and the second auxiliary antenna.
