The wireless communication system (100) includes a first device (102), e.g., a radio frequency identification (RFID) reader, having a wireless power transmitter (104), a first wireless data communications unit (106), and a first dual polarized loop antenna (110) having isolated signal feedpoints (114, 116) along a first loop electrical conductor (112). The wireless power transmitter (104) transmits a power signal having a first polarization, and the first wireless data communications unit (106) communicates using a data signal having a second polarization. A second device (202), e.g., an RFID tag, includes a second dual polarized loop antenna (210). A second wireless data communications unit (206) communicates with the first wireless data communications unit (106) of the first device (102) using the data signal having the second polarization. A wireless power receiver (204) receives the power signal having the first polarization from the wireless power transmitter (104) of the first device (102), and provides power for the second device (202).
