Abstract

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