ABSTRACT:
A millimeter wave microstrip Y-junction circulator is provided comprising a ection of microstrip dielectric substrate having a cone-shaped ferrite element mounted on one side thereof together with three, Y-junction oriented sections of microstrip conductor extending from the base of the ferrite element and an electrically conductive ground plane mounted on the other side thereof. The ferrite element is covered with a cone-shaped microstrip conductor which electrically interconnects the three Y-oriented sections of microstrip conductor. When the ferrite element is fabricated of a spinel type of ferrite, a small permanent magnet is mounted on the ground plane beneath the ferrite element to provide a unidirectional magnetic field which produces a circulator action with respect to RF energy applied to the three sections of microstrip conductor. If the ferrite element is fabricated of a hexagonal type of ferrite which produces its own internal oriented magnetic field, no external magnetic biasing means are required for the circulator.
