Abstract

A low-profile wideband circularly polarized (CP) metasurface (MTS) antenna is proposed. The MTS consists of a set of $3^{\ast} 3$ parallelograms like elements. The modal behavior of MTS is studied by using characteristic mode theory (CMA). The results show that mode 1 and mode 3 of MTS can realize wideband circular polarization. The proposed antenna size is $0.45 \lambda_{0}\times 0.45 \lambda_{0}\times 0.065 \lambda_{0}$. The simulation results show that the 3dB axial ratio bandwidth is 6.0-7.1GHz, and the −10dB impedance bandwidth is 5.2-7.13GHz. The peak gain is 7.55dBi.

基于CMA的低轮廓宽带圆极化超表面天线

提出了一种低轮廓宽带圆极化超表面(MTS)天线。MTS由一组$3^{\ast} $3 $平行四边形的元素组成。利用特征模态理论(CMA)研究了MTS的模态特性。结果表明，MTS的模式1和模式3可以实现宽带圆极化。建议的天线尺寸为0.45 \lambda_{0}\乘以0.45 \lambda_{0}\乘以0.065 \lambda_{0}$。仿真结果表明，3dB轴比带宽为6.0 ~ 7.1 ghz，−10dB阻抗带宽为5.2 ~ 7.13 ghz。峰值增益为7.55dBi。
