Abstract

Disclosed is an RF power transmission network (10). The network (10) includes at least one RF power transmitter (12a), at least one power tapping component (14a), and at least one load (20a). The at least one RP power transmitter (12a), the at least one power tapping component (14a), and the at least one load (20a) are connected in series. The RF power transmitter (12a) sends power through the network. The power is radiated from the network to be received by a device to be charged, recharged, or directly powered by the power.
