| 摘 要： | 研究了平面等角螺旋天线设计方法。该天线采用渐变线宽带巴伦馈电，实现了不平衡馈电到平衡馈电的转换，使得在整个频段内的反射损耗小于-10dB。同时通过在天线一侧设置圆台背腔，实现了天线非频变的单向辐射特性，其增益达7.5dBi。仿真及测试结果显示，该天线具有良好的驻波比及宽频带辐射特性，满足实际使用要求。

| Abstract: | The design method of the plane helical antenna is studied in this paper. This antenna is fed by a gradient linebroadband balance, which realizing the conversion from unbalanced to balance feeder and achieving the return loss be less than-10dB. Furthermore, a conical back cavity was installed at one side of the proposed antenna, which resulting the frequencyindependent characteristics in unidirection radiation and the gain of 7.5dBi. Simulation and measurement results show that theproposed antenna having the excellent characteristics of VSWR and wideband radiation and meeting the requirements ofpractical operation. |
