Design of Broadband and High Gain Metasurface Antenna Based on Characteristic Mode Analysis
为了满足C波段军事设备对高性能天线的需求,提出了一款宽带高增益超表面天线.该天线将超表面直接作为辐射器,并将超表面与高阻抗表面结构相结合,在低剖面、小型化的前提下,实现了宽带高增益的高性能;提出了超表面天线的等效电路模型;运用特征模分析,展示了一款天线从"零"到"一"的设计过程.分析了天线工程师关心的加工成本问题,并进行了天线样机的加工与测试.实测结果表明,在5～7.5 GHz(40%)的频段,反射系数小于-10 dB,峰值增益9.9 dBi,实测结果与仿真结果具有较好的一致性.
In the paper,a broadband and high gain metasurface antenna is proposed for meeting the demand of high performance antenna for C-band military equipment.The antenna uses the metasurface directly as the radiator and combines with the high-impedance-surface to achieve the high performance of broadband high gain with low profile and miniaturiza-tion.The equivalent circuit of the metasurface antenna is proposed.Characteristic mode analysis is applied to demonstrate the design process of an antenna.The processing cost,which antenna engineers concerned,is analyzed.The prototype an-tenna is processed and tested.The measured results show that the reflection coefficient is less than-10 dB and the peak gain is 9.9 dBi in the band from 5 GHz to 7.5 GHz(40%),and the measured results are in good agreement with the simula-tion results.
