The electromagnetic wave of frequency range, and resonance, the energy as much as possible for receiving the electromagnetic wave occurs with it.
In one embodiment, the electromagnetic wave of frequency range where the length of the target conducting wire, with the radio receiver signal
Wavelength meets default condition of resonance.
Depending on being the wavelength of the electromagnetic wave of frequency range where the radio receiver signal due to the length of target conducting wire, thus, it is
Ensure that the antenna that the target conducting wire is constituted has good performance, it is expected that the electromagnetic wave for receiving frequency range is most adapted to radio,
Can't be too long or too short, the wavelength of the electromagnetic wave of frequency range should where the length of the target conducting wire and the radio receiver signal
Meet default condition of resonance, in this way, the IFA antenna that the target conducting wire is constituted will be with the electromagnetism of frequency range where the radio receiver signal
Resonance occurs for wave, the energy of the electromagnetic wave of frequency range where as much as possible capable of receiving the radio receiver signal, in order to later will
The electromagnetic wave is reduced into corresponding broadcast, program etc..
In one embodiment, the default condition of resonance includes:
The ratio of the wavelength of the electromagnetic wave of frequency range is equal to pre- where the length of the target conducting wire and the radio receiver signal
If ratio.
In order to ensure the antenna that the target conducting wire is constituted has good performance, the length of the target conducting wire and the radio
The wavelength of the electromagnetic wave of frequency range should meet default condition of resonance, the length of target conducting wire and the radio receiver signal institute where signal
It is equal to preset ratio in the ratio of the wavelength of the electromagnetic wave of frequency range, and according to the resonance principle of IFA antenna, radio receiver signal place
When default resonant relationship between the wavelength and antenna length of the electromagnetic wave of frequency range is that antenna length is equal to quarter-wave,
Resonance occurs for the electromagnetic wave of frequency range where IFA antenna and radio receiver signal, thus, which should be 1/4.
More accurately, the starting point of the target conducting wire should be the crosspoint of feeding point and grounding point on the first metal wire 40
70 (namely the bifurcations 70 that can be respectively connected with respectively with the feeding point and grounding point after 40 bifurcated of the first metal wire), the mesh
The end for marking conducting wire is with the third tie point 201 on the second vertical metal edge frame 20 apart from a farther away endpoint (i.e. one
A breaking joint 60) at, and as shown in Figures 2 and 3, when on the second vertical metal edge frame 20 there are two when antenna breaking joint, due to
Third tie point 201 is located at one end of the second vertical metal edge frame 20, with the breaking joint close to, so, the end of the target conducting wire
End is with the third tie point 201 on the second vertical metal edge frame 20 apart from a farther away endpoint (i.e. a breaking joint 60)
Place.
In addition, the ratio of the wavelength of the electromagnetic wave of frequency range is equal to where the length of the target conducting wire and the radio receiver signal
When preset ratio, resonance can occur with the electromagnetic wave, receive electromagnetic wave as much as possible for the IFA antenna that not only target conducting wire is constituted
Energy, and it is zero that the corresponding input impedance of the feeding point, which is imaginary part, the pure resistance that real part is 50 ohm, just with the processing
Chip require 50 ohm of input resistance match, thus, in this case, the electromagnetic wave enter the processing chip it
Afterwards, the energy reflected is also minimum, and the heat of generation is also minimum, so the quality for the broadcast that the loudspeaker of mobile terminal 1 export
It is optimal (i.e. far less likely to occur distortion has the problems such as noise, do not know)；
Certainly, the length of the IFA antenna constituted according to the principle of IFA antenna, target conducting wire is frequency where radio receiver signal
When a quarter of the wavelength of the electromagnetic wave of section, resonance can occur with electromagnetic wave, receive electromagnetic wave as much as possible for antenna
Energy, but if the quality requirements to broadcast are not high, the length of the antenna may be the electromagnetism of frequency range where radio receiver signal
(length of such as antenna may be the wave of the electromagnetic wave of frequency range where radio receiver signal to the integral multiple of a quarter of the wavelength of wave
Long 3/4ths, half etc.), antenna still may occur humorous with the electromagnetic wave of frequency range where radio receiver signal at this time
Vibration, but it is zero that the corresponding input impedance of the feeding point, which is imaginary part, but real part be not just 50 ohm but 25 ohm, 75 ohm
Equal pure resistances, 50 ohm of the input resistance required with the processing chip and mismatch, thus, in this case, the electromagnetism
Wave is after entering the processing chip, and the energy of reflection can be more, and the heat of generation is more, so the loudspeaker of mobile terminal 1
The quality of the broadcast of output is not optimal, in fact it could happen that is distorted, has the problems such as noise, do not know.
In one embodiment, second metal wire 50 is bent n times, wherein the N is integer, and is erected after bending
The length of second vertical metal edge frame 20 described in the length of upward every section of metal wire and the described first vertical metal edge frame 10/
Match.
Since the length of second metal wire 50 is likely larger than the length of the vertical metal edge frame of the mobile terminal 1, directly
Possibly it can not be put into the terminal inner completely when placing along the vertical metal edge frame, thus, which may need
After being bent, it can be just placed into the inside of mobile terminal 1, so, shell is put into after the second metal wire 50 being bent n times
In vivo, the length and the vertical metal edge frame 20 of the first vertical metal edge frame 10/ second of vertical every section of metal wire and after bending
Length matching bend after vertical every section of metal wire length be equal to as much as possible the first vertical metal edge frame 10/ this
The length of two vertical metal edge frames 20 thus can fully reduce bending number, reduce metal wire in shell and intersect
Possibility, such as: when the target conductor length is 75cm, when the length of the vertical metal edge frame of the mobile terminal 1 is 155mm,
In order to enable the second metal wire 50 to be put into the shell, which should be at least bending 3 times.
In one embodiment, the grounding point is located at the intracorporal predeterminated position of the shell, so that the target conducting wire exists
Where receiving the radio receiver signal when electromagnetic wave of frequency range, corresponding performance parameter reaches default capabilities parameter, wherein described
Performance parameter includes: the receiving efficiency of the target conducting wire, one or more parameters in the return loss, wherein this connects
Rate of producing effects i.e. antenna efficiency refers to the power (i.e. the effectively power of converted electromagnetic wave part) and be input to that aerial radiation is gone out
The ratio between active power of antenna；And return loss is the reflected wave powers and incidence wave function of transmission line port (i.e. feed-point port)
The ratio between rate.
(namely the first metal wire 40 divides the crosspoint 70 of feeding point and grounding point on the grounding point to the first metal wire 40
The bifurcation 70 that can be respectively connected with respectively with the feeding point and grounding point after fork) this section of performance influence conducting wire, be equivalent to
The crosspoint 70 is starting point, to hold with the third tie point 201 on the second vertical metal edge frame 20 apart from farther away one
The inductance for the antenna being made of at point (i.e. a breaking joint 60) the target conducting wire of end, can adjust the performance of entire antenna
Parameter, thus, when grounding point difference, the length that this section of performance influences conducting wire will be different, and then the inductance of antenna will not
Together, the performance of antenna is naturally also different, so, which is located in shell, the target conducting wire is made to receive the radio reception
Where machine signal when the electromagnetic wave of frequency range, corresponding performance parameter reaches the predeterminated position of default capabilities parameter；In addition, this section of property
The thickness that can influence conducting wire also influences whether the performance of antenna.
In one embodiment, the centre frequency of frequency range where the length of the target conducting wire, with the radio receiver signal
The wavelength of electromagnetic wave be adapted.
In order to easily calculate the length of target conducting wire and in order to ensure target conducting wire can reception radio reception as much as possible
The length of the electromagnetic wave of frequency range where machine signal, the target conducting wire should be with the centre frequency of frequency range where the radio receiver signal
The wavelength of electromagnetic wave is adapted, and since the frequency of electromagnetic wave and the relationship of wavelength are λ=c/f, wherein f is the frequency of electromagnetic wave
It is the light velocity that rate, λ, which are the wavelength of electromagnetic wave, c, thus, when the frequency range where the radio receiver signal is that FM is broadcasted, since its frequency is logical
It is often 88-108MHz, FM centre frequency is 98MHz, so its corresponding wavelength is λ=c/f=3.06m, and then according to IFA
The resonance principle of antenna, the length of the target conducting wire should be 0.75 centimetre or so, be starting with the crosspoint 70 more accurately
Point, with the third tie point 201 on the second vertical metal edge frame 20 apart from a farther away endpoint (i.e. a breaking joint 60)
Place is that the length of the target conducting wire of end should be 0.75 centimetre or so.
