摘要

摘要: 提出了一种新型的适合于电小天线匹配的网络拓扑结构并成功地进行了验证.采用了实频数据法和直接优化法相结合的优化方法来设计电小天线的宽带匹配网络.从电小天线的特性出发,分别采用全段匹配和分段匹配的方法设计其网络拓扑结构,利用算法的寻优特性针对电小天线进行宽带匹配设计,显著提高了电小天线的使用效率和性能,并且利用仿真软件进行了计算和验证,最后对这两种方法进行了比对.设计结果表明:经过优化设计后,该电小天线的电压驻波比在100~180MHz内小于2.5且其效率基本上大于30%.所提出的网络拓扑结构非常适用于电小天线的宽带匹配,在设计电小天线以及其它天线的宽带匹配网络上具有很大的应用前景.

Abstract: A novel network topology for electrically small antennas was presented and verified successfully. An optimal design approach which combines the real frequency method and the direct numerical optimization was used to design the broadband matching network. According to the characteristic of an electrically small antenna, a network topology which can improve the efficiency of the electrically small antenna observably was designed with two methods of full-band and piecewise-band frequency matching, and the design result was computed and validated with simulation software. Finally, the two methods were compared. Results show that the voltage standing wave ratio of the antenna is below 2.5 and its efficiency is above 30% in 100~180MHz by the optimal design. The proposed network topology is especially useful in the matching of electrically small antennas and allows a good prospect of application on the designing of broadband matching networks for electrically small antennas.
