Abstract

The present disclosure discloses a WIFI antenna device, the WIFI antenna device includes a carrier, a grounding portion, a first radiation portion, a second radiation portion and a third radiation portion which all are provided on the carrier. The first radiation portion, the second radiation portion and the third radiation portion are coupled to the grounding portion. The coupling portion couples an electrical signal to the first radiation portion, the second radiation portion and the third radiation portion. The first radiation portion, the second radiation portion and the third radiation portion convert the electrical signal into the radiation signal. The first radiation portion determines a low frequency resonance point of a radiation signal emitted by the WIFI antenna device. The second radiation portion determines a first high frequency resonance point of the radiation signal. The third radiation portion determines a second high frequency resonance point of the radiation signal.
