摘要： A beam adjustable antenna device includes a dual-band antenna, a first reflection unit, and a second reflection unit. The dual-band antenna radiates or receives a signal on a first frequency or a second frequency. The first reflection unit has a plurality of first reflection boards to reflect the signal on the first frequency from the dual-band antenna. The second reflection unit has a plurality of second reflection boards to reflect an signal on the second frequency radiated from the dual-band antenna. The plurality of first and second reflection boards are arranged beside the dual-band antenna, and a plane normal vector of each first and second reflection board is directed to the dual-band antenna. The first reflection unit is closer to the dual-band antenna than the second reflection unit.
