Abstract: The invention discloses an antenna, which comprises a reference ground, a first radiation branch and a second radiation branch. The reference ground comprises a first grounding point and a second grounding point; the first radiation branch is connected to the reference ground via the first grounding point; the second radiation branch is connected to the reference ground via the second grounding point; wherein a slot is formed between the first radiation branch and the second radiation branch, and a distributed capacitance for coupling a signal is formed by coupling the first radiation branch and the second radiation branch via the slot; a connecting point is a feeding point via which one end of the second radiation branch for coupling the signal is connected to a radio frequency (RF) feed line, the feeding point arranged between the first grounding point and the second grounding point.
