Patent ID: 8144066

Claim:
A wireless communication system for data communication and power transmission, the system comprising: a first device including a wireless power transmitter, a first wireless data communications unit, and a first dual polarized loop antenna comprising a first loop electrical conductor and first and second isolated signal feedpoints along the first loop electrical conductor and separated by one quarter of a length of the first loop electrical conductor, the wireless power transmitter being coupled to the first isolated signal feedpoint to transmit a power signal having a first polarization, and the wireless data communications unit being coupled to the second isolated signal feedpoint to communicate using a data signal having a second polarization; and a second device for communications with the first device and including a second dual polarized loop antenna comprising a second loop electrical conductor and first and second isolated signal feedpoints along the second loop electrical conductor and separated by one quarter of a length of the second loop electrical conductor, a second wireless data communications unit coupled to the second isolated signal feedpoint of the second dual polarized loop antenna to communicate with the wireless data communications unit of the first device using the data signal having the second polarization, and a wireless power receiver coupled to the first isolated signal feedpoint of the second dual polarized loop antenna to receive the power signal having the first polarization from the wireless power transmitter of the first device, and to provide power for the second device.
