摘　　要：针对某阵列天线需要宽带圆极化天线阵列单元的需求,设计了一种工作于L波段轴向模右旋螺旋天线,用高频电磁仿真软件(Ansoft HFSS)优化了馈电点高度和介质支撑对天线性能影响。仿真和实测结果表明,该天线单元在31%相对带宽内,仿真和实测结果吻合较好。该轴向模右旋螺旋天线的性能完全要求,并已用于实际工程中。A kind of L-band Axial helix antenna is introduced in this article , which is designed for a broadband circularly polarized array antenna,the position of feed point and dielectric media brace bar is oplimized with Ansoft HFSS to reduce the influence to antenna performance. The results of simulation and testing shows that a good agreement with the simulation within 31% relative bandwidth. The performance of this right-circular polarization helix an- tenna meets the demands, and has already been used in real project.
