摘　　要：磁电介质天线是一种以“磁流”为辐射源的天线,某些物理特性有别于以“电流”为辐射源的金属天线,在安装于金属地平面附近的共形设计等应用场合具有独特的优势。简要回顾磁电介质天线的研究进展,阐述磁电介质天线的“镜像”、辐射效率及磁介质材料方面的基本特性,介绍了磁介质天线几种典型应用实例。The source of radiation of magneto-dielectric antennas is the"magnetic polarization current",it's different from metallic antennas with"the electric current".The magneto-dielectric antennas,in confor-mal applications near a ground plane has superior alternatives to traditional metallic antennas.In this paper,we first review the brief history of magneto-dielectric antenna,then expound the concept of the"image the-ory"and"Radiation Eficiency"of this antenna,at last introduced it's application.
