摘　　要：设计一种微带线耦合馈电的低雷达散射截面(RCS)微带天线,天线工作频带为BD2 B3。通过提高介质基板的介电常数使天线小型化,并采用微带线耦合馈电技术,经仿真和实测结果表明,天线结构简单,调频容易,辐射性能优于同轴探针馈电微带天线,并有效地缩减了天线频带内的RCS,最大缩减量达到了30dB。A low radar cross section(RCS)microstrip antenna feed by microstrip line coupling is proposed.The antenna works in BD2 B3 band.The antenna is miniaturized by increasing the di-clectric constant of the diclectric substrate,and the microstrip linc coupling fecd technology is a-dopted.The results of simulation and measurement show that the antenna is simple in structure and easy in frequency modulation,the radiation performance is better than that of the coaxial probe feed microstrip antenna,and the RCS in the antenna frequency band is reduced effective-ly,the maximum reduction is 30dB.
