SEMI-CLOSED WIRELESS DATA TRANSFER FOR ROTARY JOINTS

Systems configured to implement semi-closed wireless data transfer for rotary joints are disclosed. An example system includes first and second RF transceivers, to be included in different components of a rotary joint. The first and second RF transceivers implement elliptically (e.g., circularly) polarized antennas to realize a short distance communication link (e.g., a 60 GHz short distance communication link) between the two components of a rotary joint. The example system further includes an open-ended waveguide (OEWG) between the first and second RF transceivers, for receiving, at a first end of the OEWG, wireless signals transmitted by one of the first and second RF transceivers, transmitting the received signals through the OEWG, and radiating, at a second end of the OEWG, wireless signals indicative of the received wireless signals, to be received by another one of the first and second RF transceivers.
