Semi-closed wireless data transfer for rotary joints

A communication system, comprising:

• a first transceiver;
• a second transceiver;
• and
• an open-ended waveguide having a first end and an opposite second end, the first end being closer to the first transceiver than the second transceiver, and the second end being closer to the second transceiver than the first transceiver,
• wherein:
• the open-ended waveguide is configured to capture radio frequency (RF) radiation of a signal wirelessly transmitted by the first transceiver, propagate the captured RF radiation through the waveguide, and wirelessly transmit a signal based on the captured RF radiation propagated through the open-ended waveguide, and
• the second transceiver is configured to capture RF radiation of the signal wirelessly transmitted by the open-ended waveguide.

A communication system, comprising:

• a first transceiver;
• a second transceiver;
• and
• an open-ended waveguide having a first end and an opposite second end, the first end being closer to the first transceiver than the second transceiver, and the second end being closer to the second transceiver than the first transceiver,
• wherein the open-ended waveguide is configured to:
• receive, at the first end, a signal wirelessly transmitted by the first transceiver,
• propagate the signal received at the first end, through a propagation portion of the open-ended waveguide, to the second end, and
• wirelessly transmit, at the second end, a second signal indicative of the signal received at the first end and propagated to the second end, wherein the second transceiver is configured to receive the second signal wirelessly transmitted by the open-ended waveguide.
