摘　　要：八木天线在被用作弹体引向天线时,由于一侧柱体反射的影响,天线增益恶化严重。利用NEC软件,考虑了一侧柱体的影响,对工作在L波段的微带八木天线的增益进行了优化,使得天线增益达到15dB,并用CST仿真其结果。When Yagi antennas were applied to the projectile body as a directional antenna,the gain degenerates severely because of the reflection by the cylinder on one side.By taking the effect of cylinder on one side under consideration using NEC software,we optimize the gain of microstrip Yagi antenna working on L band to achieve a 15dB gain,and simulate the results using CST.

关 键 词：八木天线 NEC 增益 优化
