Track or the polarisation angles θ r and radio frequency energy hunting device 20 of positioning and the poliarizing antenna 113 of the radio frequency energy-transfer device 10 of polarization tracking
The polarisation angles θ h of reflection wave source 2F meet predetermined angle theta p.Second rectification unit 222 receives alternating current source Vac, and converts exchange
Source Vac is a DC source Vdc, and supplies DC source Vdc to processing unit 223.
As shown in figure 4, and coordinating refering to fig. 1~3.If radio frequency energy hunting device 20 does not have the battery of any large capacity to maintain electricity
Power；When the pole of the polarisation angles θ r and the reflection wave source 2F of radio frequency energy hunting device 20 of the poliarizing antenna 113 of radio frequency energy-transfer device 10
When change angle, θ h meets predetermined angle theta p, resonating member 23 can be closed, to save the electric power that radio frequency energy-transfer device 10 is consumed.
Therefore radio frequency energy hunting device further includes a switch module 24, and switch module 24 includes a switch unit 242 and an energy-storage units
244.Switch unit 242 is electrically connected between matching unit 213 and resonating member 23, and energy-storage units 244 are electrically connected power
The second rectification unit 222 and switch unit 242 of module 22.Alternating current source Vac rectifications are a DC source by the second rectification unit 222
Vdc, and charge to energy-storage units 244.When starting to export DC source Vdc due to the second rectification unit 222, energy-storage units 244 are still
It is uncharged, therefore energy-storage units 244 are short circuit, and processing unit 223 can not be supplied and operate required electric energy.Due to energy-storage units
244 be short circuit, therefore the control terminal (gate terminal) of switch unit 242 is low potential, and switch unit 242 is conducting state at this time.
Therefore, when switch unit 242 is connected, resonating member 23 is to increase after the signal strength of strong reflectance signal Sr is reflection wave source 2F,
Wave source 2F will be reflected via circulator unit 212 by dual-mode antenna 211 to be emitted to radio frequency energy-transfer device 10.And due to DC source
Vdc persistently charges to energy-storage units 244, therefore progressively closes off switch unit 242 in generation bias on energy-storage units 244, with
Progressively close off the electric connection between resonating member 23 and matching unit 213.It is worth mentioning, due to matching unit 213 and second
Rectification unit 222 includes the reflection signal Sr (second harmonic) that twice of frequency response is answered, and enhances two frequencys multiplication by resonating member 23
It is reflection wave source 2F to reflect signal Sr so that radio frequency energy-transfer device 10 has stronger sensitive when detecting radio frequency energy hunting device 20
Degree.
Wave source 2F is reflected when radio frequency energy-transfer device 10 receives, and adjusts the polarisation angles θ r and radio frequency of poliarizing antenna 113
For the polarisation angles θ h of the reflection wave source 2F of energy hunting device 20 after in predetermined angle theta p, energy-storage units 244 have passed through DC source
Vdc charge to can stable supplying processing unit 223 operate required electric energy.And since a current potential has been established in energy-storage units 244, because
The control terminal (gate terminal) of this switch unit 242 is high potential, and switch unit 242 is off state at this time.Therefore pass through direct current
Source Vdc, which charges to energy-storage units 244, turns off the switch unit 242, and then closes resonating member 23.At this point, 211 institute of dual-mode antenna
The electromagnetic wave source F of reception is single via the path supply processing of circulator unit 212, matching unit 213, the second rectification unit 222
Member 223 operates.Resonating member 23 is controlled by switch module 24 to be switched on or off, when can save the running of radio frequency energy hunting device 20,
Contract the electric power consumed.It is worth mentioning, when turning off switch unit 242 since energy-storage units 244 establish a current potential, poliarizing antenna
The polarisation angles θ h of the 113 polarisation angles θ r and reflection wave source 2F of radio frequency energy hunting device 20 may not adjusted in predetermined angular also
In θ p, radio frequency energy hunting device 20 is caused to fail Maximum Power Output.
It therefore, can be between energy-storage units 244 and switch unit 242 or the second rectification unit 222 and energy-storage units 233

When operating required electric energy to processing unit 223, reference voltage Vref is off switch unit 242, and then closes resonating member
23.At this point, the electromagnetic wave source F that dual-mode antenna 211 is received is by circulator unit 212, matching unit 213, the second rectification unit
222 path supply processing unit 223 operates.It is worth mentioning, the present embodiment, can be in the second rectification such as above-mentioned first embodiment
A delay cell (not shown) is added between unit 222 and energy-storage units 233.Delay cell (not shown) is delay switch unit
The time of 242 shutdowns, to extend the time that poliarizing antenna 113 adjusts polarisation angles θ r.To reach the polarizing angle of poliarizing antenna 113
