| 摘 要： | 传统的轴向模螺旋天线的方向性系数公式只考虑了螺旋直径、螺距及圈数等几个变量,忽略了反射板的尺寸和形状以及馈电方式对方向性系数的影响。简要介绍了轴向模螺旋天线的工作原理,仿真计算了反射板的尺寸和形状以及馈电方式等几个变量与螺旋天线的方向性系数的关系,加工制作了其中一种天线。实测结果与仿真结果基本一致,因此验证了仿真结果的正确性。为轴向模螺旋天线的设计提供了有价值的参考。

| Abstract: | Only several variables such as screw diameter,pitch and number of turns are involved in the formulae for expressing the directivity of conventional axial mode helical antennas,and the effects of the reflecting plate size and shape as well as the feed mode on the directivity are not considered.In the paper,a brief introduction is given to the operation principle of axial mode helical antenna;simulation is also made for describing the relationship between the directivity and the reflecting plate size and shap... |
