| 摘 要： | 文章给出了一种新型结构的缝隙加栽平面等角螺旋天线，该天线采用基于自补结构并附加缝隙的平面等角螺旋振子组成，采用矩量法对缝隙位置进行优化以改善天线的阻抗特性。根据等角螺旋天线的特性，采用一种阻抗为指数渐变的微带线——平行双线形式的宽带巴仑，并采用50Ω同轴线馈电。仿真及测试结果表明该天线具有良好的宽带特性。

| Abstract: | A novel Slot-loaded Planar Equiangular Spiral Antenna was proposed in this paper.The Slot-loaded Planar Equiangular Spiral Antenna which based on self-compensation structure was used as radiation cell.The locality of the slot was optimized by the method of moment(mom)to improve the character of the antenna.To match the character of the Planar Equiangular Spiral antenna,its balun is microstrip line-parallel wire which is exponentially gradual type and the antenna was fed by 50 ohm coaxial-cable.The wideband character of the antenna was showed in the simulation and measured data which given in the paper. |
