摘　　要：三线式宽带短波天线是一种新型的短波通信天线,为充分发挥该天线在全向通信与定向通信中的性能,本文首先采用矩量法分析计算三线天线在不同工种频率的辐射阻抗与天线方向图,并得到了天线方向性系数随工作频率变化的曲线,从而有效指导天线在全向通信或定向通信中的频率选择;利用电磁仿真软件FEKO建立了三线天线与典型地物的仿真模型,得到了典型工作频率、不同地物影响下天线方向图的畸变规律,总结出高度参数对三线天线方向图的影响最为明显,为三线天线选址架设等工程实践提供参考。Three-line HF wide band antenna is a new type of short-wave communication antenna.In order to give full play to the performance of the antenna in omni-directional communication and directional communication,this paper first analyzes and calculates the radiation impedance and antenna pattern of three-line antenna at different work frequencies by using the method of moments,and obtains the curve of antenna directivity coefficient varying with working frequency,so as to effectively guide the frequency selection of antenna in omni-directional communication or directional communication.The simulation model of three-line antenna and typical ground objects is established by using electromagnetic simulation software FEKO,and the distortion law of antenna pattern under the influence of typical working frequency and different ground objects is obtained.It is concluded that the influence of height parameters on three-line antenna pattern is the most obvious,which provides a reference for engineering practice such as location selection and erection of three wire antenna.
