Full-duplex wireless data transfer for rotary joints

A rotary joint assembly, comprising:

• a first component;
• and
• a second component, wherein at least one of the first component or the second component is to rotate with respect to the other one,
• wherein each of the first component and the second component comprises a transceiver that comprises:
• a receive (RX) antenna array to capture radio frequency (RF) radiation within a fixed RX beam and to generate an RX signal based on the RF radiation, and
• a transmit (TX) antenna array to transmit second RF radiation as a fixed TX beam, and
• wherein:
• the RX antenna array of the transceiver of the first component is to capture the RF radiation that is right-hand elliptically polarized,
• the RX antenna array of the transceiver of the second component is to capture the RF radiation that is left-hand elliptically polarized,
• the TX antenna array of the transceiver of the first component is to transmit the second RF radiation that is left-hand elliptically polarized, and
• the TX antenna array of the transceiver of the second component is to transmit the second RF radiation that is right-hand elliptically polarized.

A radio frequency (RF) transceiver for data transmission in a rotary joint assembly, the RF transceiver comprising:

• a receive (RX) antenna array to capture radio frequency (RF) radiation and to generate an RX signal based on the RF radiation, wherein the RF radiation is in an RX beam oriented in a fixed direction with respect to the RX antenna array;
• and
• a transmit (TX) antenna array to transmit second RF radiation based on a TX signal, wherein the second RF radiation transmitted by the TX antenna array is in a TX beam oriented in a fixed direction with respect to the TX antenna array, and
• wherein:
• the RX antenna array is to capture the RF radiation that is right-hand elliptically polarized and the TX antenna array is to transmit the second RF radiation that is left-hand elliptically polarized, or the RX antenna array is to capture the RF radiation that is left-hand elliptically polarized and the TX antenna array is to transmit the second RF radiation that is right-hand elliptically polarized.
