摘　　要：螺旋天线拥有较高的增益和良好的圆极化特性,因此广泛地应用在通信领域中。在卫星通信系统中,单元螺旋天线虽然拥有良好的圆极化性能,但是其增益依然难以满足系统提出的要求,而阵列螺旋天线则可以弥补这一缺陷。基于轴向模螺旋天线的基本原理,本文介绍了一种用于卫星通信中的Ku频段的单绕轴向模螺旋阵列天线。通过实测,给出了螺旋天线在12.75GHz^15.3GHz的频带内的回波损耗、轴比及增益的实测数据。仿真结果与实测结果基本一致,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。Helical antenna is widely used in the field of satellite communication due to its high gain and good circular polarization characteristics. Although single helical antenna has a good performance of polarization characteristics, its gain is still difficult to meet the requirements of the system, and helical antenna array can make up for the defect. On the basis of axial mode helical antenna theory, a kind of Ku-band axial mode helical antenna array in satellite communication system is introduced in the article, which has good performance of RL, axial ratio and gain in the frequency from 12.75GHz to15.3GHz. The agreement between the test results and the simulation results for the designed antenna indicates the correctness of the simulation, and design method presented in the paper is of valuable reference. The agreement between the test results and the simulation results for the designed antenna indicates the correctness of the simulation, and the design method presented in the paper is of valuable reference.
