An antenna device includes: a dielectric substrate; a first grounding face, a second grounding face and a third grounding face which are provided on a first face of the dielectric substrate and are isolated from each other; a first primary antenna and a first auxiliary antenna which are provided on the first face, cooperatively act with the first grounding face to operate at a first frequency range and are isolated from each other; a second primary antenna and a second auxiliary antenna which cooperatively act with the first grounding face to operate at a second frequency range and are isolated from each other; a third primary antenna which cooperatively acts with the second grounding face to operate at a third frequency range; and a third auxiliary antenna which cooperatively acts with the third grounding face to operate at the third frequency range.

Antenna device

An antenna device includes an insulating carrier and a first primary antenna having a first feeding-in section, a first auxiliary antenna having a second feeding-in section and a second grounding section, a second primary antenna having a third feeding-in section, a second auxiliary antenna having a fourth feeding-in section and a grounding face which are provided on a face of the carrier. The first primary and auxiliary antennas and the second primary and auxiliary antennas are positioned at two side edges of the carrier which are away from each other. The grounding face is positioned between both the first primary and auxiliary antennas and the second primary and auxiliary antennas. The grounding face is provided with a first grounding section adjacent to the first feeding-in section, a third grounding section adjacent to third feeding-in section and a fourth grounding section adjacent to the fourth feeding-in section.

A low profile dual-frequency antenna device comprises an insulative carrier having a first surface and a second surface which are opposite and a conductor unit, the conductor unit comprises a first conductor which is provided to the first surface and a second conductor which is provided to the second surface and connected with the first conductor, a first radiation slot as a low frequency slot antenna is formed between the first conductor and the second conductor, the first conductor is formed with a second radiation slot, a third radiation slot which is communicated with the first radiation slot and the second radiation slot, a fourth radiation slot and a fifth radiation slot, and the third radiation slot, the fourth radiation slot and the fifth radiation slot together constitute a high frequency slot antenna, the second radiation slot decides an impedance and a resonance frequency width of each antenna, a first side edge and a second side edge is oppositely positioned at a location where the second radiation slot and the third radiation slot are communicated, the first conductor has a signal feeding-in portion thereon close to the first side edge, the first conductor has a ground portion thereon close to the second side edge.
