1. A tri-band antenna module, comprising:
a substrate with a signal feed-in terminal and a ground terminal;
a first radiator;
a second radiator, wherein the signal feed-in terminal is connected to the first radiator, the ground terminal is connected to the second radiator, the first radiator comprises a first extension block and a second extension block, the second radiator comprises a third extension block and a fourth extension block, the first extension block and the second extension block are separated by a first interval, the third extension block and the fourth extension block are separated by a second interval, the first interval extends from a middle of the substrate to one side along a first direction, the second interval extends from the middle of the substrate to another side along a second direction, and the first direction is opposite to the second direction; and
a short-circuit structure connected to one end of the first extension block and one end of the third extension block and the short-circuit structure has a horizontal extension block respectively separated from the first extension block and the third extension block by a first slot and a second slot,
wherein the short-circuit structure has a first contact connected to the end of the first extension block, and an electrical length between the first contact and the signal feed-in terminal is equal to a quarter of a wavelength of a first frequency band emitted from the first radiator.
