| 摘 要： | 为了改善轴向模螺旋天线的辐射特性，在带有寄生螺旋的均匀升角轴向模螺旋天线基础上，设计了一种带有曲反射面背腔的螺旋天线，并用HFSS软件对天线的辐射特性进行了仿真分析。通过对比几种不同形式的螺旋天线的仿真结果，证明了该种螺旋天线可以有效地提高轴向模螺旋天线增益系数，圆极化一致性良好，是一种提高轴向模螺旋天线性能的有效方法。

| Abstract: | A helical antenna with a cuiving reflection cavity was designed based on symmetrical pitch angle axial mode helical antenna with a parasitic helix to improve radiation performance of axial mode helical antennas.Its radiation properties was simulated with the software HFSS.The contrast result come from the simulation of several helical antennas shows that the helical antenna can effectively improve the power gain coefficient of axial mode helical antenna.Its circular polarizable consistency is good.The method is simple and efficient for improving radiation performance of axial mode helical antennas. |
