Technical field
The present invention relates to a kind of antenna and have the electronic product of this antenna, the electronic product that relates in particular to a kind of RFID antenna and have this RFID antenna.
Background technology
Bluetooth (BlueTooth) is a kind of radiotechnics of supporting the electronic equipment short haul connection, this technology now has been applied on numerous electronic products such as mobile phone, PDA, MP3, bluetooth earphone, notebook computer, and these electronic products inside is provided with Bluetooth antenna, can carry out the wireless messages exchange between these electronic products thereby make.
Nowadays, selling on market has many electronic products that are imitations, palm off, and their shape outward appearance is the same with the product of regular manufacturer production, but the function of product and quality but have flaw, can't be protected, and consumer's None-identified are easily had dust thrown into the eyes.
In order to address the above problem, a kind of REID (RFID) has appearred.REID is automatically identified destination object and obtains related data by radiofrequency signal.The part of REID system generally comprises label (Tag), reader (Reader) and transmits the RFID antenna of radiofrequency signal between label and reader.Label is comprised of coupling assembly and chip, and each label has unique electronic code, is attached to and identifies destination object on body surface, and reader is used for reading tag information.After label enters magnetic field, accept the radiofrequency signal that reader sends, and send out by RFID antenna the product information that is stored in chip, the consumer just can distinguish therefrom that product is true and false.
Yet, existing RFID antenna takes up room greatly, thereby in electronic product easily with other element (as Bluetooth antenna), the phase mutual interference occurs, and signal radiation weak strength, need to allow reader be flattened on the product information that just can read on label on the label chips.
Summary of the invention
The objective of the invention is the defective that exists for above-mentioned prior art and deficiency provides a kind of and takes up room littlely, and can improve the RFID antenna of signal radiation intensity.
for achieving the above object, RFID antenna of the present invention, be arranged on a circuit board, be fixed with a label chip on this circuit board, this RFID antenna is connected on label chip, and be arranged on two different lateral margins of a circuit board, this RFID antenna comprises one first antenna and one second antenna, the first antenna has one first Department of Radiation, one second Department of Radiation, one connects the first connecting portion and one the 3rd Department of Radiation from the other end extension of the second Department of Radiation of this first Department of Radiation one end and an end of the second Department of Radiation, the first connecting portion, the second connecting portion and the 3rd Department of Radiation are all curved, the second antenna has one first radiation horizontal stripe, one first radiation taeniae and one connects the second connecting portion of this first radiation horizontal stripe one end and the first radiation taeniae one end.
Another object of the present invention is that the defective that exists for above-mentioned prior art and deficiency provide a kind of and take up room littlely, and can improve the electronic product with RFID antenna of signal radiation intensity.
The present invention has the electronic product of RFID antenna, has a circuit board, a RFID antenna and a Bluetooth antenna, and Bluetooth antenna is arranged on an end of circuit board; RFID antenna is arranged on two different lateral margins of and circuit board that the interval is far away different from Bluetooth antenna, this RFID antenna has one first antenna and one second antenna, the first antenna has the first connecting portion and one the 3rd Department of Radiation from the other end extension of the second Department of Radiation that one first Department of Radiation, one second Department of Radiation, connect this first Department of Radiation one end and an end of the second Department of Radiation, and the first connecting portion, the second connecting portion and the 3rd Department of Radiation are all curved; The second antenna has the second connecting portion of one first radiation horizontal stripe, one first radiation taeniae and this first radiation horizontal stripe one end of connection and the first radiation taeniae one end.
As mentioned above, RFID antenna of the present invention is arranged at the neither same lateral margin of circuit board, saves the space; And in having the electronic product of this RFID antenna, RFID antenna is arranged on place different and that the interval is far away from Bluetooth antenna, thereby can not occur to disturb and impact is worked each other; And this radio-frequency antenna signal radiation intensity is high, can allow the consumer not need to allow reader be flattened on label with regard to the product information on energy reading tag chips when distinguishing electronic product.

Embodiment
By describing technology contents of the present invention, structural feature in detail, being realized purpose and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.
The below is applied on bluetooth earphone to describe as example take RFID antenna of the present invention.
See also Fig. 1, RFID antenna of the present invention is arranged on the circuit board 1 of a bluetooth earphone, is formed by the Copper Foil etching.Be laid with the electronic devices and components (not shown) on the middle part of this circuit board 1, the bottom of circuit board 1 is provided with Bluetooth antenna 100 in the lower lip around this circuit board 1.In order to save the space of circuit board 1, the upper lateral margin of RFID antenna loop circuit capable plate 1 of the present invention and margo dexter etching form.
Please continue to consult Fig. 1, RFID antenna of the present invention is comprised of the first antenna 10 and the second antenna 20, is provided with label chip (in figure not label) between the first antenna 10 and the second antenna 20.The first antenna 10 has between the end of an end and the second Department of Radiation 12 of the second Department of Radiation 12, the first Departments of Radiation 11 of the first Department of Radiation 11 of a strip and a strip and is connected by one first connecting portion 13.The central angle that this connecting portion 13 is curved and corresponding is 73 degree, and the air line distance between its two-end-point is 2.51 millimeters.It is 3.38 millimeters with the first connecting portion 13 about the air line distance between the two-end-point of the 3rd equal Department of Radiation 14, the three Departments of Radiation 14 of the symmetrical and corresponding central angle of the central vertical line of the second Department of Radiation 12 that the other end of the second Department of Radiation 12 forms one.In the present embodiment, the transverse width of the first Department of Radiation 11, the second Department of Radiation 12 is 1 millimeter, and its longitudinal length first Department of Radiation 11 is that 9.80 millimeters, the second Department of Radiation 12 are 7.13 millimeters.
