Novel circulator design using substrate integrated coaxial line
Electronics Letters, Volume 59, Issue 15, August 2023., 2023 The contribution of this work is to propose a novel circulator design using the substrate‐integrated coaxial line (SICL) structure. The proposed SICL circulator allows the 3‐D waveguide circulator to be built in a planar form using the printed circuit board (PCB) technology.
