Abstract
An antenna device includes a differential antenna and a first balun. The differential antenna includes a first radiator, a first antenna port and a second antenna port connected to a first surface of the first radiator. Orthographic projections of the first antenna port and the second antenna port projected to the first radiator are symmetrical to a midpoint of the first radiator. The first balun is located on one side of the first surface of the first radiator, and its orthographic projection on the first plane where the first surface is located overlaps the first surface. The first balun includes a first port, a first wiring, a first coupling structure electrically connected to the first antenna port, and a second coupling structure electrically connected to the second antenna port. Neither the first coupling structure nor the second coupling structure directly contacts the first wiring.
