The poor technical problem of isolation between double antenna in the prior art.
In the embodiment of the present invention, resonator 103 is located on circuit board 104, can refer to resonator 103 and circuit board 104
Connection, such as shown in Fig. 1, or may also mean that there is L-type slotted eye in the edge of circuit board 104, resonator 103 is located at
In the slotted eye opened up.
Specifically, refer to Fig. 2, for the embodiment schematic diagram being connected with circuit board 104 when resonator 103.Now, first
Sub-portion 1031 includes the first resonant capacitance 301, the first wire 302 and the second wire 303.One end of first resonant capacitance 301 with

Wire 303 constitutes the second resonant inductance, and the first wire 302 and the second wire 303 constitute shunt inductance, the second wire 303
One end is connected with circuit board 104.Wherein, Fig. 2 is mainly for illustrating the structure of the first sub-portion 1031, therefore is not drawn into the second sub-portion
1032。
Wherein, the first resonant capacitance 301, first resonant inductance and the second resonant inductance collective effect, can
Produce the resonant frequency positioned at first frequency range.
Series arrangement electric capacity (the first resonant capacitance 301) and distributed inductance (described first in parallel in first sub-portion 1031
Resonant inductance and second resonant inductance) form composite right/left-handed transmission line (Composite Right Hand and

Wherein, the size of resonant frequency that the first sub-portion 1031 is produced can be adjusted, for example can be by changing described the
The length of one resonant inductance and/or second resonant inductance is adjusted.Preferably, first resonant inductance and/or
The length of second resonant inductance is typically less than 1/8th wavelength.Furthermore it is also possible to by changing the first resonant capacitance
301 size adjusts the impedance matching of resonator 103, and can also by changing the size of the first resonant capacitance 301 come micro-
The resonant frequency for adjusting the first sub-portion 1031 to produce.It is therefore advantageous to, the first resonant capacitance 301 can use variable capacitance, with side
Just it is adjusted.
Preferably, in the embodiment of the present invention, the electric capacity what form the first resonant capacitance 301 is actually is not limited,
Such as the first resonant capacitance 301 can be fixed capacity, or the first resonant capacitance 301 can be variable capacitance；Such as first

Fig. 3 A show when in Fig. 2 the first resonant capacitance 301 be 0.6pF when the antenna 102 of first antenna 101 and second it
Between isolation improve schematic diagram, wherein transverse axis be frequency, the longitudinal axis is return loss.In Fig. 3 A 1 represent resonance free device 103 when
Situation, 2 represent add resonators 103 after situation.
It will be apparent that return loss of two antennas when frequency is 920MHZ is -3.6dB during resonance free device, resonance is added
Device 103, and the first resonant capacitance 301 be 0.6pF when, two antennas frequency be 920MHZ when return loss be decreased obviously
For -20.1dB, it is seen that add isolation after resonator 103 and obtained obvious improvement.Therefore, the resonance in the embodiment of the present invention
Isolation of two antennas in low frequency can be substantially improved in device 103.
As shown in table 1, it is that frequency first resonant capacitance 301 in 920MHz is that (the first resonance is electric as shown in 3A by 0.6pF
Hold 301 one end ground connection), the first resonant capacitance 301 be the 0ohm one end of the first resonant capacitance 301 (as shown in 3A ground connection),
Or first antenna of the resonant capacitance 301 when being the 0.6pF one end of the ground connection of the first resonant capacitance 301 as shown in 3A (open circuit)

Table 1
From table 1 it follows that when the first resonant capacitance 301 is grounded for one end of 0.6pF and the first resonant capacitance 301,
The isolation of two antennas is obviously improved, and the radiation efficiency of two antennas increased.
When the first resonant capacitance 301 is 0ohm and one end of the first resonant capacitance 301 is grounded, the isolation of two antennas
Do not improved, and the radiation efficiency of two antennas is basically unchanged, because resonator 103 is not up to condition of resonance, it is impossible to produce
Raw resonant frequency, is equivalently employed without adding resonator 103.
When the first resonant capacitance 301 is 0.6pF and one end of the first resonant capacitance 301 is opened a way, the isolation of two antennas
Do not improved in 920MHz, and the radiation efficiency of two antennas decreases, the isolation of two antennas has in 1.06GHz
Improved, although because resonator 103 generates resonant frequency, the resonant frequency falls in 1.06GHz, therefore can not
Improve isolation during 920MHz.
Shown in Fig. 3 B, when the value for being the first resonant capacitance 301 in Fig. 2 is respectively 0.5pF to 1pF between two antennas
Isolation changes, and the transverse axis in Fig. 3 B represents frequency, and the longitudinal axis represents return loss.1 in Fig. 3 B represents the first resonant capacitance 301
Value be 1pF, 2 in Fig. 3 B represent that the value of the first resonant capacitances 301 is 0.5pF.The first resonant capacitance 301 can be found
Value it is bigger, resonator 103 produce resonant frequency can more cover more low frequency, if therefore the first resonant capacitance 301 use
Variable capacitance, then can reach the purpose for the isolation for improving two antennas under different frequency.
