Millimeter wave performance of a sliding planar backshort


A mechanically adjustable planar tuning element, for millimeter and submillimeter wave planar integrated circuits, has been developed and successfully demonstrated at 100 GHz. It functions analogously to a non-contacting waveguide backshort, with |s_(11)| ≃ -0.3 db, yet can be fabricated with the simplicity of a planar circuit and scaled for use throughout the millimeter and submillimeter wave spectrum.
