摘　　要：精确制导导弹的隐蔽性以及抗干扰特性对弹载天线的带宽提出了更高的要求,而且在安装空间受限的弹载应用场合,弹载天线必须具有较低的剖面高度才能保证导弹的气动外形及飞行性能,因此,性能优越的超宽带天线以及共形天线成为重要的研究方向。文章以圆台形金属弹体为载体,设计了对数周期天线以及小型化改进的对数周期天线共形于圆台金属弹体表面,并能够组成六元天线阵列。仿真与实验测试结果说明了该设计的合理性。The concealment and anti-jamming characteristics of precision guided missile put forward higher requirements for the bandwidth of missile borne antenna. Moreover, in missile borne applications with limited installation space, the missile borne antenna must have a lower profile height to ensure the aerodynamic shape and flight performance of the missile. Therefore, ultra wideband antennas and conformal antennas with superior performance become important research directions. In this paper, the log periodic antenna and the miniaturized improved log periodic antenna are designed, which are conformal to the surface of the metal body and can form a six element antenna array. The simulation and experimental results show that the design is reasonable.
