1. An apparatus, comprising:
- an RF power transmitter configured to generate power;
a first power tapping component coupled to the RF power transmitter, the first power tapping component configured to separate the power received from the RF power transmitter to produce a first power portion and a second power portion;
a second power tapping component coupled to the first power tapping component, the second power tapping component configured to separate the second power portion to produce a third power portion and a fourth power portion;
a first antenna coupled to the first power tapping component, the first antenna configured to transmit the first power portion received from the first power tapping component;
a second antenna coupled to the second power tapping component, the second antenna configured to transmit the third power portion received from the second power tapping component; and
a controller in communication with at least one of the first power tapping component, the second power tapping component, the first antenna, or the second antenna.

Abstract
Disclosed is an RF power transmission network. The network includes at least one RF power transmitter, at least one power tapping component, and at least one load. The at least one RF power transmitter, the at least one power tapping component, and the at least one load are connected in series. The RF power transmitter sends power through the network. The power is radiated from the network to be received by a device to be charged, re-charged, or directly powered by the power.
