研制了一类未见报道的二茂铁有机磁/BLT系微波陶瓷(OPM/BLT)磁性复合材料,用理论计算和相位延迟法得到的有效磁导率μe及有效介电常数ε十分接近,表明理论计算是获得有机磁材μe和εe的一个简便而实用的方法,用OPM/BLT(质量分数,%)制作的微带天线在1616MHz的带宽达8.6%,几何尺寸可缩小20.7%,并有良好的增益和轴比。因此,这种新型的有机磁复合材料可用最简单的结构设计实现微带天线的小型化与宽带化,在军工和高科技产品上有重要的应用价值。
A novel as yet unreported magnetic composite, ferrocenyl magnet/BLT microceramics(ie. OPM/BLT) were prepared,the effective permeability(/le) and effective dielectric constant (e e) of composite were measured by theory and phase delay method, the result shows that the experimental results are in good agreement with that of the theory. However,the theory caculates was a simple and practical method for and e,: obtanted, on the other hand the band-width was 8.6 and can be used to reduce geometric dimension of microstrip antenna (m(OPM)/m (BLT)=20/80) by 20.7% in 1616MHz,their good gain and axial ratio are also obtained. There- fore,small-size as well as width-band of microstrip antenna were obtained by simple structural design,and have important value in application for military industries and high-tech products.
