摘要：
A novel thin film type hybrid transmission-line device with a magnetic/dielectric multilayer structure was developed. The magnetic/dielectric hybrid micro strip-line consisted of a top aluminum strip line, the CoZrNb/Polyimide multilayer structure, and bottom aluminum ground plane on the Al2O3 substrate. The hybrid micro strip-line exhibited a large wavelength shortening effect. For example, the wavelength ratio of the hybrid transmission-line and free space was below 7%. Therefore, a quarter wavelength distributed constant line devices, such as impedance converter, BALUN and filter, will be miniaturized using the new hybrid transmission-line, because of its large wavelength shortening effect.
