摘要：
A wireless-power transmitter including an antenna including a plurality of power-transfer points, The antenna is configured to operate in multiple modes. The multiple modes include a standby mode and a single receiver power-transfer mode. The standby mode provides a signal to the antenna at predetermined time intervals. The signal causes the antenna to transmit electromagnetic energy that is below a threshold amount, and produce an electric field that is substantially equally distributed at each of the power-transfer points. The single receiver power- transfer mode is activated upon a wireless power-receiver coupling with one of the plurality of power-transfer points such that (i) a portion of the electric field is greater at the one of the plurality of the power-transfer points than at any other of the power-transfer points, and (ii) electromagnetic energy is transferred from the antenna to the wireless power-receiver at the one of the plurality of the power-transfer points.
