VHF宽带小型化套筒天线的优化设计

Optimal design of broadband miniature VHF sleeve antennas

研究了VHF宽带小型化套筒天线的设计与制作。采用遗传算法与模拟退火法相结合的优化方法 ,对套筒天线的结构参数以及宽带匹配网络的元件值进行一体化设计。分别采用外插收敛法、[Z]矩阵插值法以及小波变换法来提高矩量法分析计算天线的速度。

In this paper, a novel optimal-designing approach, which combines the genetic algorithm (GA) and the simulating annealing method (SA), is applied to the synthesis of sleeve antennas. The antenna parameters and matching network parameters are optimized simultaneously. The convergence acceleration methods, the [ Z ] matrix interpolation, and the Daubechies discrete wavelet transform are used in the method of moment for the fast and accurate computation The success of the proposed procedure is demonstrated through its application to the design of two broadband miniature sleeve antennas.
