摘要
长波发射天线一般可以看作是顶加载单极天线,常见的天线形式有伞形天线及倒锥型天线。本文以倒锥型天线中最常见的四塔倒锥天线为例,分析了其组成及设计过程中的关键参数选取,并通过数值计算方法给出了一个具体方案;在该方案的基础上,进行了缩比模型试验,验证了天线设计的准确性,掌握了该型天线的特点和设计方法。
The long-wave transmitting antenna can be regarded as a top loaded monopole antenna and a common form of antenna has the umbrella antenna and inverted-cone antenna. Based on the four tower inverted-cone antenna as an example, the composition of antenna is introduced and the selection of the key parameters is discussed, and a specific solution is presented by the numerical analysis method. Based on the scheme, the scale model test is carried out, the accuracy of antenna design is verified, and the characteristics and design method of the modified antenna are mastered.
