Blade antenna device

Abstract

A blade-shaped antenna device is suitable for connection to a grounding element. The blade-shaped antenna device includes a blade-shaped antenna. Each of the opposite sides of the blade-shaped antenna has a side edge and two oblique edges. The junction of the two oblique edges together forms a grounding terminal. The grounding terminal is used to mount a grounding element. Neither of the two oblique edges is parallel to the side edge.

Claims

1. A blade antenna device suitable for connection to a grounding component, comprising: a blade antenna having a side edge and two oblique edges on opposite sides, the junction of the two oblique edges forming a grounding terminal, and the grounding terminal being disposed on the grounding component; wherein the side edge is parallel to the grounding component, and the two oblique edges are not parallel to the side edge.

2. The blade antenna device as described in claim 1, wherein each of the two inclined sides forms an angle with the grounding member, and the angle is an acute angle.

3. The blade antenna device as described in claim 2, wherein the angle is between 15 degrees and 55 degrees.

4. The blade antenna device as described in claim 1 further includes an antenna housing having a base and two housing members, wherein the base of the antenna housing is disposed on the grounding member, the two housing members are assembled and disposed on the base, the two housing members together form an accommodating space, and the blade antenna is located in the accommodating space.

5. The blade antenna device as described in claim 4 further includes a plurality of fasteners that are sequentially inserted from one side of one of the two housings onto the other side of the blade antenna and the other of the two housings.

6. The blade antenna device as claimed in claim 4 further includes an N-type connector, wherein the N-type connector is disposed on the side of the base opposite to the blade antenna and is electrically connected to the blade antenna.

7. The blade antenna device as claimed in claim 4, wherein the height of the blade antenna device is between 144.2 mm and 150.2 mm.

8. The blade antenna device as claimed in claim 1 further includes a pin disposed at the ground terminal and used for electrically connecting the grounding element.

9. The blade antenna device as claimed in claim 1, wherein the voltage standing wave ratio of the blade antenna device is less than or equal to 2.

10. The blade antenna device as claimed in claim 1, wherein the gain of the blade antenna device is greater than or equal to 2 dBi.
