Abstract
The utility model relates to a novel remote control key antenna, in particular to an automobile remote control key antenna, which is arranged on a PCB and comprises an annular antenna and an antenna. The annular antenna is contacted with the PCB, and the antenna and the annular antenna form a certain angle. Since the antenna forming a certain angle along with the annular antenna is arranged on the annular antenna based on the annular antenna, the utility model realizes the purposes of improving the antenna radiation direction pattern and reducing concave points, thereby increasing the antenna gain.
Description
Technical field
The utility model relates to a kind of automobile remote-control key antenna.
Background technology
In the design of the automobile remote-control key of routine, all adopted the design of PCB loop aerial.Loop aerial has is convenient to design, low cost, the advantage little to staff coupling, but since the user position and the direction of key is uncontrollable in use, cause the gain on some direction less than normal, concave point appears on directional diagram.Influence client's use, just under some special angle and assurance mode, can't open car door.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of radiation pattern that improves, and improves the remote-control key antenna of antenna gain.
The technical solution of the utility model is: the utility model is arranged on the PCB, comprises loop aerial that contacts with PCB and the antenna that is provided with at an angle with loop aerial.
Described antenna can be many, is arranged on the loop aerial both sides.
Described antenna is vertical mutually with loop aerial.
The utility model has the advantages that: the utility model is provided with and its antenna at an angle on loop aerial by on the basis of loop aerial, reaches and improves radiation pattern, reduces the purpose of concave point, to improve antenna gain.
Description of drawings
Fig. 1,2 is a structural representation of the present utility model
1 is that PCB, 2 is that loop aerial, 3 is antenna among the figure.
Embodiment
Execution mode one
As shown in Figure 1, the utility model loop aerial 2 is arranged on the PCB1, establishes antenna 3 perpendicular to loop aerial 2 in a side of loop aerial 2.
Execution mode two
As shown in Figure 2, the utility model is established the antenna 3 perpendicular to loop aerial 2 in the both sides of loop aerial 2.
Extension elongation, the radical of above antenna 3 are provided with flexibly according to the different remote-control key of various models, and antenna 3 also can be certain angle of inclination with loop aerial 2 and be provided with.
Claims (3)
1. novel remote-control key antenna is arranged on the PCB, it is characterized in that, comprises loop aerial (2) that contacts with PCB (1) and the antenna (3) that is provided with at an angle with loop aerial (2).
2. novel remote-control key antenna according to claim 1 is characterized in that described antenna (3) can be many, is arranged on loop aerial (2) both sides.
3. novel remote-control key antenna according to claim 1 and 2 is characterized in that, described antenna (3) is vertical mutually with loop aerial (2).
