摘　　要：提出了一种加载双层金属方环电磁超材料天线罩的高增益微带天线。该天线罩位于矩形微带天线正上方30 mm处,仿真结果显示,它将微带天线辐射波球面波前修正为准平面波波前,从而使天线增益提升了2.5 dB。同时,该天线罩具备的宽带频率选择特性降低了天线雷达散射截面(RCS)。A high gain microstrip antenna loaded with double layer metal square ring electromagnetic metamaterial radome is presented.The radome is located at 30 mm above the rectangular microstrip antenna,which fixes the spherical wavefront of the microstrip antenna radiation wave into the quasi plane wave front.The simulation results show that the antenna gain is increased by 2.5 dB.Meanwhile,the broadband frequency selection characteristics of the antenna cover reduce the Radar Cross Section(RCS)of the antenna.
