摘　　要：提出了一种小尺寸弹载双波段不同辐射方向图天线。其中天线体积为41×24×1.5mm3;在2.15GHz到2.25GHz工作频段内与弹轴垂直的面上辐射方向图近似全向方向图,而在12.3GHz到12.9GHz工作频段内其弹轴下方的辐射方向图近似锥形方向图。给出了具体设计尺寸、仿真和实测方向图及电压驻波比。A dual-band antennas（from 2.15 GHz to 2.25 GHz and from 12.3 GHz to 12.9 GHz）with size 41×24×1.5mm3 is presented,these designs exhibit nearly omnidirectional radiation patterns with the vertical axis surface of Missile at 2.15 GHz to 2.25 GHz band and nearly cone-shaped radiation pattern in the bottom of missile at 12.3 GHz to 12.9 GHz band.Both simulated and experimental results are presented with the size,voltage standing wave ratio and radiation patterns.
