Abstract
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.
Claims12
A beam adjustable antenna device, comprising:
- a dual-band antenna, radiating or receiving a signal on a first frequency or a second frequency;
- wherein the first frequency is higher than the second frequency;
- a first reflection unit, having a plurality of first reflection boards to reflect the signal on the first frequency from the dual-band antenna;
- a second reflection unit, having a plurality of second reflection boards to reflect the signal on the second frequency from the dual-band antenna;
- wherein the first reflection unit is closer to the dual-band antenna than the second reflection unit;
- wherein 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;
- wherein each of the first and second reflection boards is coupled to a respective switch;
- when the switch is turned on, one of the first and second reflection boards corresponding to the switch is grounded, so that a beam field of the dual-band antenna corresponding to the first frequency or the second frequency is changed.
