Abstract :
The design and experimental results for a four-port circulator based on a novel concept using a distributed coupling phenomenon are presented. The circulator consists of an E-H junction cascaded with the section of two coupled lines containing ferrite magnetized in the propagation direction. The choice of configuration and the design procedure are described. An isolation of 15 dB in the 26-30-GHz band is obtained, confirming the validity of the theory and design procedure.<>
