Abstract
The utility model discloses a Bluetooth antenna and relates to an electronic device antenna. The Bluetooth antenna comprises a helical antenna. Two rows of parallel via holes are disposed on a double-sided PCB. The helical antenna forms a three-dimensional helical structure with the bridge connection of the via holes. The Bluetooth antenna has advantages of ingeniously utilizing the bridge effect of the via holes on the double-sided PCB so as to achieve three-dimensional connection between the top surface and the bottom surface of the PCB, thereby forming the Bluetooth antenna with the three-dimensional helical structure, well and effectively receiving Bluetooth signals under the circumstance of not increasing any electronic components and cost, and achieving characteristics of simple structure, low cost, and high practicality.
Description
Technical field
The utility model relates to electronic equipment antenna, and specifically a kind of Bluetooth antenna, is applicable to mobile phone, panel computer, vehicle audio etc. with the electronic equipment of Bluetooth antenna.
Background technology
Bluetooth technology was universal in recent years, in the terminal of communication apparatus, panel computer, automobile audio etc. field, bluetooth receiving equipment uses very general, and current bluetooth reception antenna is seldom used separated antenna element device, great majority designs be by the direct cloth of Bluetooth antenna on PCB, can reduce costs like this, conserve space.At present, the PCB Bluetooth antenna structure of generally using is the planar rectangular curve on pcb board, because the area of the acknowledge(ment) signal of PCB flat plane antenna is little, and also has certain directivity, receives that Bluetooth signal ability is weak, efficiency is low.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of Bluetooth antenna, and reception Bluetooth signal ability is strong, efficiency is high.
The utility model is realized with following technical scheme: a kind of Bluetooth antenna, comprise a spiral helicine antenna, and on double-sided PCB board, be provided with the parallel via hole of two rows, spiral helicine antenna forms spiral structure by via hole bridge joint.
The beneficial effects of the utility model are: the function served as bridge that has utilized cleverly double-sided PCB board via hole, the Top face and the solid between Bottom face that have realized pcb board connect, thereby form a kind of Bluetooth antenna of spiral structure, in the situation that not increasing any electronic devices and components, not increasing cost, can better, more effective reception Bluetooth signal; Simple in structure, cost is low, and practicality is very high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
In figure: 1, double-sided PCB board, 2, via hole, 3, spiral helicine antenna.
Embodiment
As shown in Figure 1, a kind of Bluetooth antenna has a spiral helicine antenna 3, is provided with the parallel via hole of two rows 2 on double-sided PCB board 1, and spiral helicine antenna 3 forms spiral structure by via hole bridge joint.
Via hole 2 in the present embodiment adopted the conventional PCB manufacture craft in via hole hole to make.
Innovative sufficient some design features of utilizing PCB plate of this practicality, utilize PCB upper by the conventional manufacture craft in via hole (via) hole, spatially spiral formula antenna structure form, broken the version of the plane curve design of traditional Bluetooth antenna in PCB layout, by plane to stereochemical structure, a qualitative leap, Bluetooth signal reception good, practicality is very high.
