A recently granted patent (Publication Number: US11888204B2) discloses a novel waveguide design comprising a first return conductor, a second return conductor, and a signal conductor arranged in a specific stepped configuration to define curves. The signal conductor is positioned between the first and second return conductors and includes multiple conductive layers forming distinct curves. Additionally, a reference plane with periodic openings overlapped by the signal conductor is included in the waveguide structure.

Furthermore, the patent describes a transmission line and a coplanar waveguide utilizing similar stepped conductive layers to define curves in the return conductors and signal conductor. The transmission line includes a signal conductor in an intermediate dielectric layer, while the coplanar waveguide features capacitively coupled edges in the return conductors and signal conductor. These innovative designs aim to enhance the performance and efficiency of waveguides and transmission lines by optimizing the arrangement of conductive layers and curves within the structures.
