| 摘 要： | 针对龙伯透镜的诸多优点,设计了适用于工作频段8～13 GHz的平面波激励源与9～11 GHz的喇叭馈源激励源的龙伯透镜。依据龙伯透镜的设计思想和方法,并结合遗传算法,对其进行优化设计,达到最优化效率。通过CST软件对龙伯透镜的几何尺寸进行仿真,得出了龙伯透镜的各种性能指标。仿真结果表明：平面波激励源经龙伯透镜作用后很好的聚焦于一点,而喇叭馈源在其作用后则得到平面波的特性。

| Abstract: | Aiming at the disadvantages of luneberu lens antenna,the paperproposes the design suitable for the plane wave as the driving source applicable to 8～13 GHz frequency wave bands and the horn feed as the driving source applicable to 9～11 GHz.According to the design on and method for luneberu lens antenna,in combination with the genetic algorithm,this paper gives the optimal design,and by modeling and optimizing the geometric size of the antenna with CST software,the various performance indexes of the antenna are obtained.The simulation results show that the electromagnetic wave drived by plane wave could focus,through the antenna,on one point while drived by horn feed gives the character of plane wave. |
