摘要
电磁波束调控一直是电磁场领域的一个重要的研究课题。人工电磁表面具有的灵活控制等效电磁参数的性质,为替代传统介质透镜的三维曲面或者相控阵的有源器件,实现结构简单的平面微波器件提供了一种有效的方法。研究了基于小型化的空间带通滤波器(MEFSS)的X波段平面微波透镜,阐述了微波透镜的原理与使用MEFSS构造微波透镜的方法。电磁仿真结果表明它在9~10GHz宽带范围内具有良好的波束聚焦稳定性与聚焦增益,可以用于宽带高增益天线、多波束天线设计。
Electromagnetic wave beam control is always an important research topic in electromagnetic fields.The artificial electromagnetic surface is able to control equivalent electromagnetic parameter flexibly which provides an alternative solution for replacing 3-D curved surface of traditional medium lens or active device of phased-array to build a simple planar microwave device.This paper studies a planar microwave lens of X-band based on miniaturized element frequency selective surface(MEFSS),expounds the theory of microwave lens and the method constructing microwave lens by using MEFSS.The electromagnetic simulation results show that it has a high focusing gain and stable focal range from 9 GHz to 10 GHz,which enable its application to wideband high gain antenna and multi-beam antenna.
