Abstract

In this paper we investigate the influence of dielectric and magnetic losses of an Epoxy bonded Yttrium Iron Garnet (YIG-Epoxy) composite substrate on the performance of a reconfigurable microstrip patch antenna. The antenna under investigation is a microstrip patch antenna printed on a 60/40 w/w% YIG-Epoxy composite substrate and controlled by an externally applied DC magnetic field. It is observed that high dielectric losses of the composite substrate can dramatically deteriorate the radiation efficiency of the proposed antenna in the demagnetized state, while in the magnetized state the magnitude of the resonance linewidth (ΔH) of the composite substrate is the main parameter responsible for the reduction or improvement of the radiation efficiency. Considerable effort has been made to fabricate a YIG-Epoxy substrate with improved properties regarding dielectric loss tangent and magnetic resonance linewidth. The prototyping and characterization of a reconfigurable patch antenna on the “improved” YIG-Epoxy substrate is also presented.

磁介质衬底对可重构贴片天线效率的影响

本文研究了环氧键合钇铁石榴石(YIG-Epoxy)复合衬底的介电损耗和磁损耗对可重构微带贴片天线性能的影响。所研究的天线是一个微带贴片天线，印刷在60/40 w/w%的yig -环氧复合基板上，由外部施加的直流磁场控制。研究发现，复合衬底的高介电损耗会显著降低天线在退磁状态下的辐射效率，而在磁化状态下，复合衬底的共振线宽(ΔH)的大小是降低或提高天线辐射效率的主要参数。已经付出了相当大的努力来制造具有改善介电损耗、正切和磁共振线宽性能的yig -环氧基板。在“改进”的YIG-Epoxy基板上进行了可重构贴片天线的原型设计和表征。
