Patent ID: 8587386

Claim:
A high isolation waveguide switch having a closed position and an open position, comprising: a stator having a proximate side and a distal side, said stator further comprising: a first, second, third, and fourth port uniformly spaced around said distal side and extending through said stator, each of said ports further comprising a mounting flange on said distal side configured to attach to a waveguide; a central axle having a proximate end and a distal end, said central axle centrally located on and perpendicular to said proximate side of said stator and fixedly attached thereto by said distal end of said central axle; a rotor having a fastener rotably attached thereto and adapted to engage the proximate end of the central axle, said rotor further comprising: a proximate side; a distal side; a first channel and a second channel disposed within said rotor, each configured to conduct electromagnetic energy along its length, wherein said first channel connects from the first port to the second port and said second channel connects from the third port to the fourth port when the rotor is in a first orientation, and said first channel connects from the second port to the third port and said second channel connects from the first port to the fourth port when said rotor is in a second orientation; and where said fastener opens and closes said high isolation waveguide switch, wherein when in said open position said rotor freely rotates around said central axle and when in said closed position said shielding surfaces contact said stator to form a plurality of EMI shields between said first channel and said second channel.
