摘　　要：为了获得较好的端射向辐射特性,提出一种基于模拟退火法的Delta天线优化设计方法.通过优化Delta天线各单元的长度和倾角,并引入地面反射参数的经验公式和基频法计算天线的辐射总场,以获得一定尺寸范围内的最优天线参数.实际设计了工作于1～30 MHz的Delta天线,测试结果表明,该方法是一种快速有效的Delta天线优化设计方法.Delta antenna is a typical antenna for ionospheric vertical detection, and its radiation performance is mainly determined by the length and obliquity of the basic elements. To obtain better radiation characteristics an optimization method for designing Delta antenna is proposed, and the method is based on simulated annealing （SA） and the basic frequency method. The measured results using an optimized antenna at 1-30 MHz show that the optimization is fast and effective.
