摘要
为了加速天线的设计及应用过程,用EDA软件工具对预设计的天线先进行仿真是一种有效的方法。这里讨论宽带双鞭天线及匹配网络的优化设计,根据直接优化法的思想,利用CST和ADS软件对天线及匹配网络参数优化。分析匹配网络电特性。设计及试验结果表明,天线系统在工作频带内具有良好的辐射效率和阻抗宽带性能,证明了这里所采用的方法是切实可行的。
In order to accelerate process of the antenna design and application, using EDA software tools for the pre-designed antenna simulation is an effective way. The optimized design with hrodaband two whips antenna and matching network is discussed,according to the thought of direct optimization method, using CST and ADS on the antenna and matching network optimization. By using simulative software to analyze the electric characteristics about the matching network. The design and experimental results show that the antenna system has a good performance in impedance and broadband, good radiation efficiency which has proved the given methods is viable.
