Electronic device

An electronic device, comprising:

• a printed circuit board comprising a first dielectric board and a second dielectric board that are disposed in a stacked manner;
• a feed point and a ground point;
• and
• a plurality of radiators comprising a first radiator, a second radiator, and a third radiator, wherein
• a first end of the first radiator and a first end of the second radiator are opposite to each other, and form a first gap;
• a second end of the first radiator and a first end of the third radiator are opposite to each other, and form a second gap;
• the feed point and the ground point are disposed on the first radiator;
• the ground point is disposed in a central region of the first radiator or the plurality of radiators;
• the feed point is disposed between the central region and the first end of the first radiator;
• in response to an electrical signal being fed at the feed point, the first radiator, the second radiator, and the third radiator jointly generate at least one resonance;
• and
• the first radiator is disposed between the first dielectric board and the second dielectric board, the second radiator is disposed on an upper surface of the first dielectric board, and the third radiator is disposed on a lower surface of the second dielectric board.
