| Popis: | An ultra-high-bandwidth Y-junction circulator is demonstrated using the “continuous tracking” operation. The analysis is developed starting from Bosma's circulation conditions and based on several previous works that have been investigated in order to complete the methodology and enhance the circulator's performances. Indeed, the broadband junction impedance matching is illustrated and the real inhomogeneous internal field $\mathrm{H}_{\mathrm{i}}$ is considered in the electromagnetic (EM) analysis. A complete EM and magnetostatic (MS) co-simulation is presented and validated by experimental results of a prototype operating on the [4.5 GHz-10.5 GHz], i.e. on an 80% of bandwidth. The performances are also compared to the previous works presented in literature in terms of bandwidth and insertion losses. |
