【Abstract】 In order to miniature receiving array antennas of HF surface wave radar, an improved genetic algorithm was applied to optimize the design of HF broad band antenna loaded with lumped components and matching network in 4～8MHz. The disturbing effect of loading circuit parameters and their locations on antenna′s electrical characteristics was analyzed specifically according to antenna engineering and practice. And the analysis illustrates that the loading parameters derived are not quite sensitive to the disturbance after the optimization.更多还原
