摘　　要：针对短波接收天线的小型化问题,用弯折偶极子的方式来增大电流路径[1],设计出一种小型化的对数周期天线[2]。以加载电感和附加枝节的结构方式,调节振子阻抗虚部大小,拓宽了对数周期天线的低频带。该天线工作于3~30MHz频段,天线尺寸仅为22.85m×17.8m。仿真结果表明:该天线平均增益主用频段达10dBi,驻波小于2.5,波束宽度大于80°。In view of the miniaturization of the shortwave receiving antenna,the current path is increased by bending the dipole,and a miniaturized log-period antenna is designed.With the structure of loading inductance and additional branches,the size of the imaginary part of the log-periodic antenna.The antenna works in the 3~30 MHz frequency band,and the antenna size is only 22.85m×17.8m.Simulation results show that the average gain of the antenna main frequency band is up to 10dBi,VSWR is less than 2.5,and the beam width is greater than 80°.
