Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most from start to finish
Same or similar label represents same or similar element or has the element of same or like function.Below with reference to attached
The embodiment that figure describes is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
Embodiment one
See Fig. 1, the multifrequency antenna of the present invention include Department of Radiation and the earth point 8 being connected with described Department of Radiation respectively and
Distributing point 9, described Department of Radiation includes that the first Department of Radiation 5 extended from described distributing point 9 is connected with described first Department of Radiation 5
The second Department of Radiation 6, and produced because of ghost effect by described first Department of Radiation 5 or the second Department of Radiation 6 and and described connect
The 3rd Department of Radiation 3 that place 8 connects.
The mid frequency of described first Department of Radiation 5 work is 1800MHz, the mid frequency of described second Department of Radiation 6 work
For 900MHz, described 3rd Department of Radiation 3 is by described first Department of Radiation 5 and described second Department of Radiation 6 and the ghost effect on ground
Produce, parasitic capacitance and stray inductance the resonance that formed and produce, can be by described 3rd Department of Radiation 3 of regulation and ground
Between position obtain the frequency range of the passive antenna wanted, in this programme, the mid frequency of described 3rd Department of Radiation 3 is
2100MHz。
The GSM900 of the preferred 2G of the present invention, the WCDMA B1 2100 of GSM1800,3G design described multifrequency antenna, have with
Lower each side reason:
One, smart machine can improve spectrum utilization ability in being operated in this lower frequency range of GSM900.Such as, exist
During 35MHz, 1% bandwidth is only 350kHz；And when 800MHz, 1% bandwidth is about 8MHz.
Its two, utilize the smart machine of this frequency range, the size of its component can be greatly lowered, it is achieved the hand-held system of miniaturization
System, preferably to solve the difficult design that described intelligent watch limited space is brought.
Its three, in terms of physical characteristic from the point of view of, 900M frequency spectrum is relatively low, and wavelength is longer, but transmit distant.From covering
Radius aspect, Digital Cellular System is little in 900MHz frequency range line loss consumption, therefore under same physical condition, the covering of GSM900
Radius ratio is bigger.
Its four, preferably 1800MHz its may be used for in-door covering, or closely base station covers and absorbs traffic, effectively divides
Load network load, can be additionally used in the data services such as GPRS, EDGE simultaneously.The working channel of GMS900 has 124, DCS1800's
Working channel has 374, uses multifrequency can extenuate the frequency spectrum resource of anxiety.
But, for the application of smart machine, in expanding to higher scope, also there is physical constraints.Main consideration
It is that the order of severity of multipath fading increases with channel frequency and is greatly increased.When frequency higher than 10GHz, easily cause serious
Path loss.Therefore, the frequency of more than 10GHz is inapplicable for smart machine.In actual applications, frequency is more than 1GHz
Above mobile communication, is necessary for considering the multipath fading that various factors brings.
As can be seen here, the GSM900, GSM1800 of the preferred 2G of the present invention designs described multifrequency antenna and is capable of described intelligence
The miniaturization of energy equipment, i.e. can design the communication of the most compatible multiple frequency ranges in the confined space of described intelligent watch.And it is right
In the WCDMA B1 2100 of 3G, its be the GSM900 antenna part by 2G or GSM1800 antenna part and the ghost effect on ground and
Produce, parasitic capacitance and stray inductance the resonance that formed and produce, it meets the integrity demand of frequency range.Same with this
Time, the preferred above-mentioned each frequency range of the present invention has also taken into account the coverage of the communication quality of described smart machine, design cost, network
And spectrum utilization ability.
Referring to Fig. 3 and Fig. 4, as seen from the figure, described multifrequency antenna is inverse-F antenna, and described inverted F shaped antenna has structure letter
Single, lightweight, can conformal, low cost of manufacture, radiation efficiency be high, easily realize the particular advantages such as multiband work.Described inverted f sky
Line be the vertical unit end of inverted l antenna as described in Fig. 2 the second sub-frequency detail 321 and perpendicular detail plus one
Inverted L structure the 3rd sub-frequency detail 322 as shown in Figure 2 and described 4th sub-frequency detail 323 are constituted.It uses additional described the
Three sub-frequency details 322 and described 4th sub-frequency detail 323 structure adjust the coupling of antenna and feeding coaxial lines.This antenna has
Low profile structure, radiation field has horizontal and vertical two kinds polarization, additionally, due to compact conformation and the direction radiation spy such as there is
Property, its good grounding design can be effectively improved the work efficiency of antenna simultaneously.
Please continue to refer to Fig. 3, described multifrequency antenna 3 includes described first Department of Radiation 31 containing main radiation portion, containing collateral radiation
Described second Department of Radiation 32 in portion and described 3rd Department of Radiation 33 containing time Department of Radiation.The frequency range that described main radiation portion accepts
Signal is the main signal that accepts of described multifrequency antenna, and described collateral radiation portion and secondary Department of Radiation mainly realize assisting described multifrequency
Antenna accepts the function of other frequency band signals to widen the working frequency range of described smart machine, it is ensured that described smart machine work frequency
Section integrity and multiformity, for " secondary " therein and " secondary " are relative to described main radiation portion, described collateral radiation portion with
Primary-slave relation is not considered between secondary Department of Radiation.
Further, described first Department of Radiation 31 is due to the shorter main linearly cabling of its length, and the relatively strong event of its radiation
It is in the layout of the tip edge of lateral surface of described bezel, cluster away from the position of human arm.Described second its length of Department of Radiation 32 is relatively
Long, therefore take roundabout cabling form to be in the layout of on the table ear of described intelligent watch to save space, and cabling carries out overstriking and sets
Meter, to avoid going out to have high frequency to occur pressing close to arm.
To sum up can obtain, described multiple frequency antenna structure is simple, low cost of manufacture, performance are good and can realize multiband work.Cause
This, described multifrequency antenna is applicable to multiple smart machine, is particularly suited for the smart machine such as intelligent watch of miniaturization, and it can
Communicate with the most compatible 2G/3G and reduce the radiation to human body electromagnetic wave.
