Abstract

The design and experimental results for a novel three-port finline circulator are presented for the frequency range 26-40 GHz. The circulator consists of a T^E-junction cascaded with the section of ferrite coupled slot finlines magnetized in the propagation direction. The T^E-junction structure refers to a transition from a unilateral single slot finline taper to a coplanar line region via a tapered center conductor. The design procedure for the structure is described and confirmed by experimental results. The proposed structure belongs to the family of the distributed coupled ferrite line nonreciprocal devices suitable for application in the millimeter-wave range
