Discussion on the efficiency of Microwave Wireless Power TransmissionOA
The efficiency of a Microwave Wireless Power Transmission(MWPT)system is a key metric for evaluating its performance.However,current efficiency measurements alone do not fully represent system performance.When designing MWPT systems,it is essential to take into account the sizes of the transmitting and receiving antennas as well as the transmission distance,rather than focusing solely on efficiency,in order to develop an optimal energy transmission solution.This paper introduces the aperture-to-distance ratio as a critical parameter.By thoroughly analyzing its impact on MWPT energy transfer efficiency,we can better understand system behavior under varying antenna sizes and transmission distances,thereby guiding system optimization and improving overall performance.Studies indicate that the aperture-to-distance ratio not only reflects energy concentration capability but is also linked to system complexity and cost.Therefore,incorporating this ratio enables a more objective assessment of MWPT system performance and provides valuable insights for system design.
