Applications of Contactless Characteristics of Gap Waveguides in Mechanical Reconfigurability

Paper in proceeding, 2023

Three reconfigurable transmission lines (TLs) (a sheath rectangular waveguide, a movable rectangular waveguide, and a universal-joint circular waveguide) have been proposed in this work to extend the applications of gap waveguide technology in the domain of mechanical reconfigurability. These three reconfigurable TLs enable movements of waveguide ports through mechanisms of sheathing, displacement, and rotation without wave propagation leakage, and thereby provide possibilities for antenna mechanical reconfigurability.
