Abstract
The wireless communication system includes a first device, e.g. a radio frequency identification (RFID) reader, having a wireless power transmitter, a first wireless data communications unit, and a first dual polarized loop antenna having isolated signal feedpoints along a first loop electrical conductor. The wireless power transmitter transmits a power signal having a first polarization, and the first wireless data communications unit communicates using a data signal having a second polarization. A second device, e.g. an RFID tag, includes a second dual polarized loop antenna. A second wireless data communications unit communicates with the first wireless data communications unit of the first device using the data signal having the second polarization. A wireless power receiver receives the power signal having the first polarization from the wireless power transmitter of the first device, and provides power for the second device.
