Rotating circular waveguide channel for foldable electronic devices

A rotatable circular waveguide structure, comprising:

• a first circular waveguide coupled to a display portion of an electronic device and having a first outer diameter;
• a second circular waveguide coupled to a chassis portion of the electronic device and having the first outer diameter,
• wherein the first circular waveguide and the second circular waveguide are coupled to one another via a coupling section that is routed through a hinge of the electronic device;
• and
• a sleeve coupled between (i) a first transition portion formed in the first circular waveguide having a first conductive surface formed between a second outer diameter, which is less than the first outer diameter, and an inner diameter of the first circular waveguide, and (ii) a second transition portion formed in the coupling section, the second transition portion including a second conductive surface,
• wherein the first transition portion is configured to fit within the second transition portion to provide a first rotatable junction,
• wherein the sleeve facilitates, during rotation of a section of the first circular waveguide and the coupling section with respect to one another, galvanic coupling to be maintained by way of physical contact being maintained between the first conductive surface of the first transition portion and the second conductive surface of the second transition portion abutting one another, and
• wherein the first circular waveguide, the second circular waveguide, and the coupling section are configured to enable a propagation of data signals between the chassis portion and the display portion of the electronic device.
