Technical field
The utility model relates to a kind of GSM antenna structure, and in particular, the utility model relates generally to a kind of GSM antenna structure of watch style wearable device.
Background technology
At present, the volume requirement of market to Wearable is more and more higher, and when volume-diminished, the area of circuit board is also more and more less.And when circuit board area diminishes effectively time, circuit anti-interference ability will sharply decline.Theory and practice proves, when the length of antenna is 1/4 of radio signal wavelength, and when the length on antenna ground is greater than 1/4 of radio signal wavelength, the transmitting and receiving conversion efficiency of antenna is the highest.The interference of aerial radiation to circuit board is minimum.And the length on the length of antenna and antenna ground decides according to the frequency of transmitted and received signal and wavelength.With the centre frequency 935MHZ of GSM900 frequency range correspondence transmitting and receiving, the wavelength of corresponding radio signal just can be calculated with formula below:
Wavelength=300000 kilometer/935MHz=300000000/935000000=300/935=0.32 meter
Be exactly the length on corresponding optimal antenna length and aerial radiation ground again divided by 4 by the wavelength calculated:
1/4 wavelength=0.32 meter/4=0.08m=8cm
And when the length reduction of circuit board is within 1/4 wavelength 4cm, in GSM900 frequency range, circuit board sharply worsens by external interference ability, cause the radiation efficiency of antenna non-low, generally such product is tested through reality, is below 20dB at the Net long wave radiation value TRP of GSM900 frequency range, and this can increase in the power consumption of artificial delivery product, shorten stand-by time, often the problems such as not online.
Utility model content
One of the purpose of this utility model is above-mentioned deficiency, a kind of GSM antenna structure of watch style wearable device is provided, cause product antijamming capability not enough to expect to solve GSM antenna structure in prior art, affect emission effciency, also easily cause the technical problems such as the power consumption increase of product.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
The utility model a kind of GSM antenna structure of watch style wearable device is provided, described antenna access table body, described antenna extends along the watchband of table body, for by table body equipment circuit board by antenna transmission with receive radio signals, the end of described table body is also provided with Antenna extender ground, the circuit board of body equipment is shown, for improving the radiation efficiency of low-frequency range antenna in described Antenna extender ground also access.
As preferably, further technical scheme is: described Antenna extender ground is extended by the end of table body to watchband, is all placed in the inside of watchband described antenna and Antenna extender.
Further technical scheme is: described antenna and Antenna extender ground be placed in respectively show body two ends on.
Compared with prior art, one of the beneficial effects of the utility model are: by setting up Antenna extender ground and the length of prolongation table body antenna simultaneously, effectively improve the antijamming capability of watch style wearable device in GSM900 low-frequency range, thus improve the emission effciency of antenna, making at the Net long wave radiation value TRP of GSM900 low-frequency range is more than 25dB, avoid causing the power consumption of product to increase because low frequency Net long wave radiation value is too low, thus reach increase signal strength signal intensity, extend the object of product stand-by time.A kind of GSM antenna structure provided by the utility model is simple simultaneously, and can use on all kinds of watch style wearable device, range of application is wide.
Accompanying drawing explanation
Fig. 1 is the structural representation for illustration of the utility model embodiment;
In figure, 1 for table body, 2 be antenna, 3 for Antenna extender ground, 4 for watchband, 5 be circuit board.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in figure 1, an embodiment of the present utility model is a kind of GSM antenna structure of watch style wearable device, this antenna structure comprises table body 1 and antenna 2, antenna 2 is accessed table body 1, and antenna 2 is extended, for the circuit board 5 by table body 1 equipment by antenna 2 launching and receiving radio signal along the watchband 4 of table body 1; What is more important, the end of table body 1 is also provided with Antenna extender ground 3, and the circuit board 5 of body 1 equipment is shown, for improving the radiation efficiency of low-frequency range antenna 2 in Antenna extender ground 3 also access.Aforesaid antenna 2 and Antenna extender ground 3 be preferably placed in respectively show body 1 two ends on
In the present embodiment, by setting up the length of antenna 2 prolongedly and simultaneously prolongation table body antenna, effectively improve the antijamming capability of watch style wearable device in GSM900 low-frequency range, thus improve the emission effciency of antenna, making at the Net long wave radiation value TRP of GSM900 low-frequency range is more than 25dB, avoid causing the power consumption of product to increase because low frequency Net long wave radiation value is too low, thus reach increase signal strength signal intensity, extend the object of product stand-by time.
On the other hand, for effectively promoting the antijamming capability of antenna in low-frequency range, preferably above-mentioned Antenna extender ground 3 is extended by the end of table body 1 to watchband 4, and, for not affecting the normal use of wearable device, antenna 2 and Antenna extender ground 3 all need be placed in the inside of watchband 4.
The utility model designs mainly for GSM900 frequency range.According to antenna theory emulation and actual test result, radio signal will reach good radiation results on antenna, preferably meets the following conditions:
1, antenna equivalent length is 1/4 of radiation signal wavelength;
2, in order to reduce aerial radiation interference, circuit board 5 length is minimum can not lower than 1/4 of radiation signal wavelength;
The aerial ripple myopia of radio signal is the wavelength=light velocity/frequency

The wavelength of radio signal in circuit board 5 of 935MHZ is
Wavelength=(300000 kilometers/935MHz)/√ 4.5=0.32/2.12=0.15m
Be exactly minimum circuit plate 5 length of correspondence again divided by 4 by the wavelength calculated:
1/4 wavelength=0.15m rice/4=0.037m=3.7cm
Suppose that the length of circuit board 5 is X
So optimal antenna equivalent length is 8(cm)
Minimum circuit board 5 length needing compensation is 3.7-X(cm), when X is greater than 3.7cm, without the need to compensating;
