摘要
本文介绍了现有小功率短波台站的天线使用情况和小功率短波垂直极化天线的基本理论,分析了台站现有短波垂直极化天线的发射特性。通过电磁仿真比较研究,探讨改善小功率短波垂直极化天线覆盖场型的可行方案,为以后的小功率短波台站天线优化改造提供技术指导和参考。
This paper introduces the antenna usage in the existing low-power short-wave stations and the basic theory of low-power short-wave vertical polarization antenna. In addition, the radiation characteristics of cage antenna in the existing stations are simulated. And then the paper discusses a feasible scheme to improve the radiation pattern performance of cage antenna. The discussion provides useful guidelines and references for antenna design in low-power short-wave stations.
