1. An electronic device, comprising:
a metal housing, having a slot, the slot including an opening end and a closed end, the slot having a first slot wall and a second slot wall, the first slot wall and the second slot wall disposed on two sides of the opening end, respectively, the first slot wall being disposed between the second slot wall and the closed end, and there being a predetermined distance between the first slot wall and the closed end;
a carrier board, disposed in the metal housing; and
a radiating element, disposed on the carrier board, the radiating element including a feeding portion, a first radiating portion, and a second radiating portion, each of the first radiating portion and second radiating portion having an open end, the first radiating portion and the second radiating portion being connected to the feeding portion, the first radiating portion and the second radiating portion being directly connected with each other, the feeding portion, the first radiating portion, and the second radiating portion jointly forming a T-shaped structure, the first radiating portion and the second radiating portion extending in different directions, a vertical projection of the radiating element on the metal housing at least partially overlapping the slot, the feeding portion connected to a feeding element and a signal being fed into the feeding portion through the feeding element, so that the radiating element is used to excite the metal housing to generate at least one resonance frequency;
wherein a first segment line parallel to the first slot wall is defined between the first slot wall and the closed end, a distance between the first segment line and the first slot wall is half of the predetermined distance, the feeding portion is disposed in the region between the first segment line and the first slot wall, and the first slot wall is closer to the first segment line than the second slot wall;
wherein the first radiating portion is used to generate a first operating frequency band, the second radiating portion is used to generate a second operating frequency band, and the first operating frequency band is different from the second operating frequency band;
wherein the open end of the first radiating portion is located between the closed end and first segment line, and the open end of the second radiating portion is located between the first slot wall and the first segment line;
wherein the slot is L-shaped, a first axis and a second axis are defined according to the extending directions of the slot, the first axis is parallel to the extending direction of the slot toward the opening end, the second axis parallel to the extending direction of the slot extending toward the closed end, the slot defines a first slot region along the first axis and a second slot region along the second axis, the radiating element is used to excite the metal housing to generate a first resonance frequency band in the first slot region and generate a second resonance frequency band in the second slot region, and the first resonance frequency band is greater than the second resonance frequency band.
