An antenna device includes a first antenna, a second antenna, a main short portion and a grounding portion. The first antenna and the second antenna are disposed in a PCB to radiate signals. The main short portion is disposed between the first antenna and the second antenna. The main short portion is further electrically coupled to the grounding portion. The main short portion adjusts current between the first antenna and the second antenna. Thus, the main short portion reduces interference between the first antenna and the second antenna. The first antenna includes a first feeding portion, a first short portion and a first coupling portion. A first end of the first feeding portion is suspended in the air. The first coupling portion is disposed in a first storage space. The first coupling portion is electrically insulated from the first short portion and the grounding portion.

Antenna device

An antenna device includes a first antenna and a second antenna. The first antenna and the second antenna are disposed in a PCB to radiate signals. The first antenna includes a first ground portion, a first short portion and a first feeding part. The first short portion and the first ground portion are electrically coupled together to form a first storage space. Further, THE first storage space has a first notch. The first feeding part is disposed in the first storage space. The first feeding part and the first short portion are not contacted through any metallic conductors. The first feeding part and the first ground portion are not contacted through any metallic conductors. A communication device is also provided.

Antenna device and communication device

A housing assembly of an electronic device includes an outer housing, an inner housing mounted to the outer housing, a first waterproof film positioned between the outer housing and the inner housing, and a second waterproof film spaced from the first waterproof film. The first waterproof film, the outer housing, and the inner housing cooperatively define a first cavity of the housing assembly. The second waterproof film, the inner housing, and the first waterproof film cooperatively form a second cavity of the housing assembly. The first and second waterproof films provide the housing assembly an excellent waterproof property. The electronic device using the housing assembly is also described.
