Patent ID: 8279129

Claim:
A transverse device array phase shifter operable at microwave or millimeter-wave frequencies, comprising: a dielectric substrate having a top surface and a bottom surface, the bottom surface having a conductive ground plane layer formed thereon, the top surface having a conductive patterned layer formed thereon to define a conductor pattern; an array of active tuning elements cascaded along a propagation direction in a spaced arrangement along a longitudinal extent; a housing structure including a bottom housing structure with a planar conductive bottom surface for contacting the bottom conductive layer on the bottom surface of the dielectric substrate, and a top housing structure fabricated with a channel which extends along the propagation direction in the longitudinal extent and provides clearance for the active tuning elements; and a bias circuit connected to the array of active tuning elements, wherein the propagation direction is a direction of a traveling electromagnetic wave.
