ABSTRACT:
A two-state microwave signal phase shifter comprising a first signal conductor disposed in a first plane, a second signal conductor electromagnetically coupled to the first signal conductor and disposed in overlapping relationship therewith in a second plane parallel to and spaced from the first plane, a ground plane element disposed in a third plane parallel to and spaced from the first plane, third and fourth signal conductors connected to the second signal conductor and disposed perpendicular to the second signal conductor; fifth and sixth conductors disposed in the second plane; switching diodes connecting the opposite ends of the third and fourth conductors to the fifth and sixth conductors; and a seventh conductor connected to the fifth and sixth conductors.
