摘　　要：本文对采用超材料的概念来提高多波段微带贴片天线的带宽进行了研究。所设计的天线由作为周期谐振器辐射单元的矩形贴片和在地面上蚀刻的3x3互补对称分裂环谐振器(CSSRR)组成。互补对称分裂环谐振器加载的地面通过收集贴片产生的电场来增加增益,起到了透镜的作用。文章详细讨论了所提出的周期谐振器天线的等效电路模型,并利用HFSS对结果进行了数值计算。所设计的周期谐振器天线可以工作在C波段和X波段,并且与传统天线相比,具有较高的带宽。Metamaterial concept is used to enhance the bandwidth of multi-band microstrip patch antennas.The designed antenna consists of rectangular patch as meta-resonator radiator with 3×3 complementary symmetrical split ring resonator(CSSRR)etched in ground plane.The CSSRR loaded ground plane acts as lens to increase the gain by collecting fields generated by the patch.Equivalent circuit model of proposed meta-resonator antenna is discussed in detail and the results are calculated numerically using HFSS software.The designed meta-resonator antenna can work with multi-band in C-band and X-band with good characteristics,and provide the enhanced bandwidth with more notches as compared to conventional antennas.
