A bracket-antenna assembly (3a) for transmitting and receiving electromagnetic waves as well as supporting a liquid crystal display of an electronic device is disclosed. The bracket-antenna assembly is formed by a side of a loop bracket (3) and includes a first antenna (41) and a second antenna (42) having the same structure with the first antenna and arranged symmetrically to the first antenna on the side of the bracket. Each of the antennas includes two inverted-F antennas operating at different frequency bands. A remained portion of the bracket acts as a grounding portion (30) of both the first and the second antennas.
