Slot antenna device

A slot antenna device, comprising:

• a conductive shell, having an inner surface and an outer surface facing away from each other and having a slot and a chamfer structure, wherein the slot penetrates through the conductive shell from the inner surface to the outer surface, and the chamfer structure is formed at an intersection of the slot and the inner surface;
• an inner frame, disposed on the inner surface of the conductive shell, wherein the inner frame has an overflow groove, an opening of the overflow groove faces the inner surface, and a distance from the overflow groove to the chamfer structure is greater than or equal to 0 mm and less than or equal to 2.0 mm;
• an adhesive glue, disposed between the conductive shell and the inner frame, wherein a part of the adhesive glue is located in the overflow groove;
• and
• a circuit board, disposed on the inner frame, wherein the circuit board and the slot form an antenna radiator.
