Patent ID: 11374434

Abstract:
A radio frequency energy-harvesting apparatus is applied to a radio frequency energy-transmitting apparatus with a location detection function. The radio frequency energy-harvesting apparatus includes a direct current signal receiving-processing unit, a rectification and harmonic generation unit, and a radar wave receiving-transmitting unit. The rectification and harmonic generation unit is electrically connected to the direct current signal receiving-processing unit. The radar wave receiving-transmitting unit is electrically connected to the rectification and harmonic generation unit. The radio frequency energy-transmitting apparatus transmits a radar wave scanning to a space; after the radar wave receiving-transmitting unit receives the radar wave, according to the radar wave, the radar wave receiving-transmitting unit generates an alternating current signal; the radar wave receiving-transmitting unit transmits the alternating current signal to the rectification and harmonic generation unit; the rectification and harmonic generation unit generates a radar reflection harmonic wave and a direct current signal.
