Antenna unit and electronic equipment

The invention relates to an antenna unit and electronic equipment. The antenna unit comprises a dielectric substrate, a grounding layer, a first radiation arm, a second radiation arm, a first director, a second director and a feed structure. Coupling feeding is carried out on the gap opening through the feeding structure, electromagnetic waves obtained through feeding coupling are reflected to the first radiation arm and the second radiation arm through the grounding layer, further improvement of radiation directivity is facilitated, and through the radiation opening with the gradual change rule formed by the first radiation arm and the second radiation arm, the ultra-wideband radiation characteristic can be realized, and the flattening of a reflection curve is facilitated; besides, the first director guides the direction of receiving and transmitting electromagnetic wave signals of the first radiation arm, and the second director guides the direction of receiving and transmitting electromagnetic wave signals
