Abstract

A wireless communications system includes a first transceiver with a first phased array antenna panel having first circularly polarization reconfigurable receive transmit antennas, where the first circularly polarization reconfigurable receive transmit antennas form a first receive beam based on receive phase and receive amplitude information provided by a first master chip and form a first transmit beam based on transmit phase and transmit amplitude information provided by the first master chip. The wireless communications system may include a second transceiver having second circularly polarization reconfigurable receive transmit antennas where the second circularly polarization reconfigurable receive transmit antennas form a second receive beam based on receive phase and receive amplitude information provided by a second master chip, and form a second transmit beam based on transmit phase and transmit amplitude information provided by the second master chip.
