Abstract

A dual-band antenna unit, comprising: a first radiation unit; a second radiation unit; a first signal feed-in unit electrically connected to the first radiation unit; and a second signal feed-in unit, electrically connected to the second radiation unit; wherein the first radiation unit, the second radiation unit, the first signal feed-in unit and the second signal feed-in unit are disposed in the dual-band antenna unit. Therefore, the number of antennas can be reduced to achieve lower cost while remaining the signal transmission quality.

Claims

1. A dual-band antenna unit, comprising:

a first radiation unit comprising a first metal tube and a second metal tube electrically connected in series;

a second radiation unit comprising a third metal tube and a first metal wire electrically connected in series;

a first signal feed-in unit comprising a first feed-in unit and a first grounding unit, the first grounding unit being electrically connected to the first metal tube and the first feed-in unit being electrically connected to the second metal tube; and

a second signal feed-in unit comprising a second feed-in unit and a second grounding unit, the second grounding unit being electrically connected to the third metal tube and the second feed-in unit being electrically connected to the first metal wire;

wherein the first radiation unit, the second radiation unit, the first signal feed-in unit and the second signal feed-in unit are disposed in the dual-band antenna unit.

2. The dual-band antenna unit as recited in claim 1, wherein the first metal wire is extended from the second feed-in unit.

3. The dual-band antenna unit as recited in claim 1, wherein the first signal feed-in unit and the second signal feed-in unit are co-axial wires.

4. The dual-band antenna unit as recited in claim 1, further comprising a housing so that the first radiation unit, the second radiation unit, the first signal feed-in unit and the second signal feed-in unit are disposed in the dual-band antenna unit.

5. The dual-band antenna unit as recited in claim 4, wherein the first radiation unit and the second radiation unit are arranged in series in the housing.

6. The dual-band antenna unit as recited in claim 4, wherein the housing is made of plastic.

7. The dual-band antenna unit as recited in claim 1, wherein the first metal tube, the second metal tube and the third metal tube are copper tubes.

8. The dual-band antenna unit as recited in claim 1, wherein the first metal wire is a copper wire.

9. A dual-band antenna unit, comprising:

a first radiation unit comprising a first metal tube and a first metal wire electrically connected in series;
