Antenna device
Abstract:
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.
