ABSTRACT:
A millimeter wave switchable microstrip Y-junction circulator is provided comprising a monlithic, wye-shaped ferrite element disposed on one surface of a section of microstrip dielectric substrate having three, Y-junction oriented sections of microstrip conductor on the same one substrate surface and an electrically conductive ground plane on the opposite substrate surface. The ferrite element has a central right prism-shaped portion with two equilateral triangular-shaped prism bases and three rectangular prism faces and three downwardly-sloping arm portions which extend radially outwardly from the prism faces of the central portion. The top base of the ferrite element central portion and the top surface of the ferrite arm portions which do not rest on the substrate are provided with microstrip conductors which cooperate with the ground plane to convey millimeter wave signals applied to the three Y-junction oriented microstrip sections on the substrate to the ferrite element central portion. Each ferrite arm portion has a lateral opening therethrough and a single turn of electric control current wire is threaded through all three openings to create a magnetic field in the ferrite central portion which causes it to act as a circulator to selectively couple the three microstrip sections on the substrate.
