摘　　要：根据弹载探测系统的探测要求，设计了一款毫米波介质阵列天线。将6个介质天线单元均匀安装在弹体侧向一周，通过波导馈电形成阵列天线。阐述了基本理论和设计方法，给出了设计尺寸。ANSOFT HFSS仿真结果表明，该阵列天线辐射方向图轴向前倾30°，周向方向图接近圆，且在37．8—38．9GHz的工作频段内VSWR〈2，最高增益可达到11dB。该阵列天线适用于相关工程。According to probing requirement of missile-borne antenna probing system, a millimeter-wave dielectric antenna array was de- signed. Six antenna units were evenly mounted on projectile circumferential that were feed through waveguide, forming medium array anten- na. The basic theory and design methods were described and design dimensions were given. ANSOFT HFSS simulation results show that the axial radiation patterns lean forward 30°, the circumferential radiation pattern is nearly circular, the VSWR 〈 2 at working bandwidth 38 39 GHz. and the antenna highest gains reach 11 dB. This array antenna can be used for related nroiects.
