Abstract: A multi-junction stripline circulator, comprising a housing with a cavity structure and a plurality of stripline junction circuits stacked within the cavity structure and connected in a cascade arrangement. Each stripline junction circuit comprises a stripline conductor having a plurality of ports, where one of the ports is connected to a port of a stripline conductor of each consecutive junction circuit in a cascade arrangement, and a pair of ferrite elements sandwiching the stripline conductor therebetween. The multi-junction stripline circulator further comprises one or more center ground planes, each having radial arms connected to ground. Each of the center ground planes are disposed between two consecutive stripline junction circuits in said cascade arrangement.
