Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with the accompanying drawings and be embodied as
The present invention is further detailed explanation for mode.
One of core idea of the embodiment of the present invention is, it is provided that the protection device of a kind of wireless user terminal, in such as protection
Coupled antenna is increased so that coupled antenna can accurately couple with the antenna of wireless user terminal, whereby on set, containment vessel
Increase the intensity that wireless user terminal antenna receives, launches signal.
The mode of enhancing signal of the present invention is based on electric coupling principle.Fig. 1 be the present invention wireless user terminal antenna with couple
The electric coupling principle schematic of antenna.As it is shown in figure 1, wireless user terminal include antenna 2, antenna 2 at feed point 22,
By feeder 21, antenna is accessed IC circuit board, receive and send the signal of wireless user terminal.Wireless user
Install in the appropriate area (calling coupling regime in the following text) of terminal and can couple sky with the antenna 2 of wireless user terminal is coupled
Line 1.Under shortwave, ultrashort wave frequency band, it not open-circuit condition between antenna 2 and coupled antenna 1, after coupled antenna is set,
There is the parasitic capacitance 3 that can not ignore between coupled antenna and antenna, coupled antenna 1 couples with antenna 2.Coupled antenna 1
After coupling with antenna, coupled antenna 1 provides a low-impedance path for electric current, thus electromagnetic wave is passed through coupled antenna
1 radiate, or by the signal of the base station such as base station, the router combined reception by coupled antenna 1 with antenna 2
Enter the reception circuit of wireless user terminal, promote the efficiency of wireless user terminal antenna whereby, strengthen wireless user terminal
The intensity of signal.Capacitive reactance is the biggest, and the amount of coupling between coupled antenna 1 with antenna 2 is the biggest, the letter to wireless user terminal
The reinforced effects of number intensity is the best.
The size of parasitic capacitance depends on the impact of the factors such as antenna shape, size and relative position with coupled antenna.
Capacitive reactance between antenna and coupled antenna is:
Wherein, j constant,
F is electromagnetic wave signal frequency,
C is capacitance.
As shown in formula above, after wireless user terminal determines, signal frequency used is known as one and determines frequency, then sky
Capacitive reactance between line and coupled antenna is inverse relation with capacitance C of parasitic capacitance 3.And capacitance C of parasitic capacitance 3
Relevant with the shape of antenna 2, size and position relatively with coupled antenna 1.I.e. to the wireless use using signal specific
For the terminal of family, it is possible to by adjusting the relative position of coupled antenna 1 and antenna 2, the shape of coupled antenna 1, coupling
Arbitrary parameter in the size of antenna 1, can regulate the capacitor value between antenna and coupled antenna, i.e. adjustable wireless user
The intensity of the signal of terminal.
It should be noted that because of the signal of the applicable several different frequencies of wireless user terminal, as mobile phone can
It is suitable for the signal that a few class of 2G, 3G, 4G, wifi is different, and of a sort signal, such as 3G signal, different operators makes
3G letter frequency the most incomplete same, the signal of wifi also have 2400Hz, have 5000Hz point.Institute of the present invention
" the sending and receiving signal of wireless user terminal " stated, refers to the signal determining frequency that wireless user terminal is used,
Corresponding " the wireless user terminal sending and receiving signal wavelength " determined used in coupling regime, refers to this letter to be reinforced
Number wavelength.I.e. in technical scheme, the signal of wireless user terminal to be reinforced and coupled antenna are one_to_one corresponding: one
Individual mobile phone is in the face of the signal of different frequency, and the coupling regime of antenna is different, and the coupled antenna used is the most different.
The intensity of wireless user terminal signal of the present invention, refers to that wireless user terminal receives or sends the ability of signal,
Can be by the expression of the efficiency of antenna.
So that coupled antenna successfully couples with the antenna of wireless user terminal, the base portion of coupled antenna must be arranged on properly

It is frequently referred on " ground of mobile phone ".This earth terminal is generally the material that electric conductivity is good.It should be noted that earth terminal and couple
The most also can produce parasitic capacitance between antenna, and this parasitic capacitance can not be ignored: if taking no action to,
Also parasitic capacitance can be produced between earth terminal with coupled antenna and mating of coupled antenna and antenna will be destroyed.It is to say, one
Denier earth terminal produces parasitic capacitance with coupled antenna, and coupled antenna will be affected with the coupling effect of antenna.And because lead
The setting area of electricity material is the biggest, can affect the radiation of coupled antenna and antenna, even if there being the existence of coupled antenna,
It is also possible that the radiation efficiency of antenna is deteriorated, therefore, application claims, coupled antenna wireless user terminal to be got around
Earth terminal.It is to say, when arranging coupled antenna, the earth terminal interval in coupled antenna and user is arranged, and does not contacts.
Usually, in order to more up hill and dale away from the earth terminal of wireless user terminal, the coupled antenna position that arranges on shell on the back gets around
Earth terminal arranges the projection on face at coupled antenna, but the present invention does not Qiang Zhiyaoqiu that getting around earth terminal arranges face at coupled antenna
On projection.
