Coplanar High Impedance Wire on Ferrite Substrate: Application to Isolators

This article studies about the structure of high-impedance wires (HIWs) based on ferrite substrate coplanar waveguide (CPW). Slotted planar stubs are etched on one or two ground planes of the CPW line. Several prototype measurements have been performed showing excellent performance to implement narr...

Zusammenfassung:This article studies about the structure of high-impedance wires (HIWs) based on ferrite substrate coplanar waveguide (CPW). Slotted planar stubs are etched on one or two ground planes of the CPW line. Several prototype measurements have been performed showing excellent performance to implement narrow-band microwave isolators. These HIW components can work at low bias-field giving an easier implementation in microwave devices.
