研制了一种新型的磁性/介质多层结构薄膜混合传输线器件。磁/介质混合微带线由Al/sub 2/O/sub 3/衬底上的顶部铝带线、CoZrNb/聚酰亚胺多层结构和底部铝接地层组成。混合微带线具有很大的波长缩短效应。例如，混合传输线和自由空间的波长比低于7%。因此，四分之一波长分布常数线器件，如阻抗转换器，巴伦和滤波器，将小型化使用新的混合传输线，因为它的大的波长缩短效应。
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 Al/sub 2/O/sub 3/ substrate. The hybrid microstrip-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 device, such as impedance converter, balun and filter, will be miniaturized using the new hybrid transmission-line, because of its large wavelength shortening effect.
