    摘要： A power receiving antenna is provided, which is capable of efficiently receiving electric power from a distant power transmitting device, and allows a change of its size within a certain range. A power receiving antenna used for wireless power feeding includes: a first conductive plate; a second conductive plate that faces the first conductive plate; a feeder connecting a first end portion of the first conductive plate and a second end portion of the second conductive plate facing the first end portion; and a conductive member connecting a first other end portion opposite to the first end portion and a second other end portion opposite to the second end portion.

    摘要： A method is provided. The method is for power delivery in a wireless power system including a transmitter and a receiver. The method includes receiving, by the receiver, a focused power transmitted by the transmitter and directly measuring, by the receiver, a radio frequency (RF) power level of the focused power. The method includes determining whether the power level of the focused power exceeds a threshold and performing operations based upon the power level exceeding or not exceeding the threshold.

    摘要： Various embodiments of the present technology relate generally to wireless power systems. More specifically, some embodiments relate to the use of time reversal techniques utilizing time diversity (e.g., different multipath arrivals at the same antenna) to achieve coherency from the same transmission node. For example, instead of initiating outgoing transmissions (e.g., power signals) at the same time, various embodiments can initiate the outgoing signals from the various antennas in a staggered timing that is a reversal of the arrival times of an incoming signal. As a result of staggering the start of the outgoing signals, the signals will arrive at the destination at approximately the same time even though they have traveled different paths having different propagation delays.

    摘要： A rectenna device includes an antenna (210), a first rectifier (31) to rectify a radio frequency wave input in the antenna (210), an antenna (220), a second rectifier (32) to rectify a radio frequency wave input in the antenna (220), and a capacitive coupler (5) to form an open circuit in response to direct current and to form a short circuit in response to a fundamental wave. The first rectifier (31) includes a ground (GND) conductor (410) to be a reference potential, and the second rectifier (32) includes a GND conductor (420) to be a reference potential. The GND conductor (410) and the GND conductor (420) are connected with the capacitive coupler (5) in between. The first rectifier (31) and the second rectifier (32) are connected in series.
