Abstract:
A circulator unit comprising:a first member and a second member both being of ferro-electric material and arranged adjacent to one another; a conductive circulator pattern printed on the first or second member and arranged between the first and the second member, the circulator pattern having a first set of terminals; a first dielectric layer having a first aperture receiving the first member; a second dielectric layer having a second aperture receiving the second member; conductive strips and a second set of terminals being arranged on the first or second dielectric layer; wherein the second member extends beyond the first member on an area where the second set of terminals are provided rendering the second set of terminals accessible; wherein the first dielectric layer extends beyond the second dielectric layer, or vice versa, on an area where the first set of terminals are provided rendering the first set of terminals accessible; first and second ground conductors arranged on each side of the first and second members; and at least one device for providing a magnetic field through the first and second member.
