Influence of the Magnetic Field Nonuniformity on an X-Band Microstrip Y-Junction Circulator Bandwidth: Theory/Experiment Comparison
Résumé
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.
