摘　　要：设计了一种基于加载并联电感的新型左右手复合微带天线,利用电磁波在有耗介质中传播的色散关系,分析其只存在零阶和正阶的电磁波工作模式,通过简单调节微带天线馈电点的位置实现微带天线的单频或者双频工作。仿真和实验结果表明:这种微带天线的零阶和一阶模式电磁波的工作频率在L波段,零阶辐射模式为全向辐射模式,一阶辐射模式为定向辐射模式。A new kind of composite fight/left-handed microstrip antenna based on loaded shunt inductor is designed in this paper. Analyzing zeroth and positive order electroamagnetic wave modes with the dispersion relationship in lossy material. We realized sin- gle frequency or dual-frequency microstip antenna via adjusting only source location points; Simulated and measured results all in- dicate this micorstip antenna works well at L-band.
