Abstract
The utility model discloses a Bluetooth antenna, which comprises a first base part, a first extension part, a second extension part, a feed-in part and a grounding part. The base part presents in a rectangular plate shape; the first extension part is formed by extending one side of one end of the base part, and the second extension part is formed by extending one side of the other end of the base part and corresponds to the first extension part. The tail end of the second extension part extends to form the feed-in part and the grounding part. The base part and the first and the second extension parts form a concave structure. The Bluetooth antenna not only occupies small space, but also has high efficiency and large yield value.
Description
Technical field
The utility model relates to a kind of Bluetooth antenna, relates in particular to a kind of Bluetooth antenna that is used on the electronic communication products such as notebook computer.
Background technology
At present, Bluetooth technology is popularized in a large number at electronic products such as mobile phone, notebook computers.Along with portable needs, these electronic products develop towards miniaturization.
Yet present Bluetooth antenna takes up room greatly, and transmitting-receiving efficient is low, power is little.The curve a of Fig. 2 is the transmitting-receiving efficiency curve diagram of present a kind of Bluetooth antenna, and when frequency during at 2.4GHz, its transmitting-receiving efficient only is 21% to the curve a from figure approximately as can be known; The curve c of Fig. 3 is the curve chart of the absolute gain value of present a kind of Bluetooth antenna, and the curve c from figure is as can be known when frequency during at 2.4GHz, and its absolute gain value only is about-2.2dBi.
The utility model content
Main purpose of the present utility model is to provide a kind of Bluetooth antenna at the defective that the above-mentioned background technology exists, and this Bluetooth antenna can reduce transmitting-receiving efficient and the gain that takes up room and improve electromagnetic wave signal.
For achieving the above object, the utility model Bluetooth antenna is used to be assembled into the communications electronics product, and this Bluetooth antenna comprises a base portion, one first extension, one second extension, a feeding portion and a grounding parts.It is rectangular tabular that described base portion is, and first extension is formed by the side extension of an end of described base portion; Second extension is extended by a side of the other end of described base portion and forms and relative with described first extension.The end of second extension extends to form described feeding portion and grounding parts.Described base portion, first extension and second extension are formed a concave structure.
In sum, the utility model Bluetooth antenna is formed a concave structure by base portion, first extension and second extension, thereby just can realize the current path length that antenna is required with less space, and little thereby the utility model Bluetooth antenna not only takes up room, and efficient height, gain are big.
Description of drawings
In Figure of description:
Fig. 1 is the stereogram of a kind of embodiment of the utility model Bluetooth antenna.
Fig. 2 is the curve chart of the efficient of Bluetooth antenna shown in Figure 1 and present Bluetooth antenna.
Fig. 3 is the curve chart of the absolute gain value of Bluetooth antenna shown in Figure 1 and present Bluetooth antenna.
The description of reference numerals of each element is as follows among the figure:
Bluetooth antenna 100 base portions 1
First lateral margin, 11 second lateral margins 12
First extension, 2 second extensions 3
Embodiment
For describing technology contents of the present utility model, structural feature, the purpose of being reached and effect in detail, below exemplify embodiment now and conjunction with figs. is described in detail.
See also Fig. 1, this figure is the stereogram of a kind of embodiment of the utility model Bluetooth antenna 100.Bluetooth antenna 100 can be made or be formed by the Copper Foil etching that is printed on the circuit board by the sheet metal punching press, and Bluetooth antenna 100 is for to make with the sheet metal punching press in the present embodiment.Bluetooth antenna 100 has one and roughly is rectangular tabular base portion 1.This base portion 1 has the first relative lateral margin 11 and second lateral margin 12.
The right-hand member of described base portion 1 is positioned at and vertically extends one before the side direction of first lateral margin 11 and roughly be the rectangular first tabular extension 2.The right side of this first extension 2 flushes with the right-hand member edge of base portion 1.The left end of described base portion 1 is positioned at second extension 3 that vertically extends a bar shaped before the side direction of first lateral margin 11, thereby base portion 1, first extension 2 and second extension 3 are formed a concave structure.The left side of second extension 3 flushes with the left end edge of base portion 1.Described first extension 2 is parallel with second extension 3 and be in the same plane.Described base portion 1, first extension 2 and second extension 3 are in the same plane.
The front end of described second extension 3 bending downwards extends an adjacent feeding portion 4 and a grounding parts 5.The end of feeding portion 4 is connected with a match circuit (not shown), and this match circuit is an inductance, thereby reaches the required resonance frequency of this Bluetooth antenna 100.
When the utility model Bluetooth antenna 100 was used to communicate by letter, it was the concave structure that described base portion 1, first extension 2 and second extension 3 are formed that base portion 1, first extension 2 and second extension 3 are used for electromagnetic wave signal and path of current that the headend frequency is 2.4GHz.The curve b of Fig. 2 is the transmitting-receiving efficiency curve of the utility model Bluetooth antenna 100, and when frequency was 2.4GHz, its transmitting-receiving efficient was about 28% to the curve b from figure, far above the transmitting-receiving efficient 21% of present curve a as can be known; The curve d of Fig. 3 is the curve of the absolute gain value of the utility model Bluetooth antenna 100, and the curve d from figure is as can be known when frequency is 2.4GHz, and its absolute gain value is about-1.8dBi, far above absolute gain value-2.2dBi of present curve c.As seen from the figure, the utility model Bluetooth antenna 100 can improve the efficient and the yield value of bluetooth module greatly.
In sum, the utility model Bluetooth antenna 100 is formed a concave structure by base portion 1, first extension 2 and second extension 3, thereby just can realize the current path length that antenna is required with less space, it is little that thereby the utility model Bluetooth antenna 100 not only takes up room, and efficient height, yield value are big.
