Abstract

We propose a theoretical approach aimed at accurately describing the electromagnetic (EM) response of a microstrip Y-junction circulator. This analysis is predictive since it relies on the insertion of both the nonuniformity of the static field of polarization and the ferrite material magnetization state. We fabricated proof-of-concepts to compare the responses issued from two available EM analyses, namely our approach and the HFSS software one. The key-role of a rigorous modeling of the microstrip Y-junction circulator is highlighted through a comparison of simulation data and experimental results
