摘　　要：本文设计了1种带状线馈电的新型小型化超宽带印刷偶极子天线。该天线由印刷在介质基板上双面对称的辐射贴片以及中间的带状线馈电巴伦组成。通过对偶极子臂进行曲折设计以及加载寄生贴片和吸波结构,显著地拓展了天线阻抗带宽,同时实现了天线的小型化。结果表明,该天线能在109%相对带宽(0.7GHz~2.4GHz)内实现VSWR<2,同时天线横向尺寸和纵向高度仅为最低频工作波长的0.18倍和0.13倍。A novel miniaturized ultra-widenband printed dipole antenna fed by strip line was designed in this paper.The antenna is composed of a double-sided symmetrical radiators printed on a substrate and a strip-line feed balun in the center.By zigzagging the dipole arm and loading the parasitical patch and absorbing structure,the impedance bandwidth of this antenna can be enhanced and the size of this antenna is reduced.The results show that the antenna can realize 109%relative bandwidth(0.7GHz~2.4GHz)with VSWR<2,and the transverse size and longitudinal size of the antenna are only 0.18 times and 0.13 times of the lowest frequency working wavelength.
