An antenna is provided, which includes: a main stub, a first parasitic stub, and a second parasitic stub. The first parasitic stub and the second parasitic stub are respectively arranged on two sides of the main stub. The first parasitic stub and the second parasitic stub are configured to excite resonances to improve main resonance efficiency or expand bandwidth. A frequency of the resonance excited by the first parasitic stub is greater than a frequency of a resonance excited by the main stub. A frequency of the resonance excited by the second parasitic stub is less than the frequency of the resonance excited by the main stub.

Antenna and mobile terminal

An electronic device includes an antenna unit having an antenna body having a feed point and a ground point between a first end and a second end. The antenna body has an operating band with a resonance of a first wavelength. An electrical length of the antenna body from the feed point to the ground point is greater than or equal to ¼ and less than ½ of the first wavelength. An electrical length from the first end to the feed point is greater than or equal to ⅛ and less than or equal to ¼ of the first wavelength. An electrical length from the second end to the ground point is greater than or equal to ⅛ and less than or equal to ¼ of the first wavelength. The antenna body is adapted to operate in a slot mode and in a wire mode.
