摘　　要：设计了一种超宽带弹载共形天线,工作频段内天线驻波比(VSWR)≤2.5,辐射性能优良。共形天线采用的形式为对数槽线天线。天线由柔性天线面和圆柱形腔体组成,天线中的槽线振子单元增加了移相缝,进行相应相位补偿,解决了宽频段范围内天线方向图开裂的问题。圆柱形腔体内部装填蜂窝式吸波材料,减少了装载弹体对天线性能的影响。该共形天线能够满足系统的使用要求。This paper designs an ultra-wide band(UWB)missile-borne conformal antenna,the antenna standing wave ratio(VSWR)isn't more than 2.5 in the frequency band and has good radiation performance.The conformal antenna uses the type of log-periodic folded slot antenna(LPFSA).The antenna is composed of flexible antenna surface and cylindrical cavity.The phase-shifting slot is used in each folded slot dipole element to perform the corresponding phase compensation,which solves the problem of antenna pattern cracking in the wide frequency band.Honeycomb wave-absorbing material is filled in the cylindrical cavity,which reduces the influence of loaded missile body on antenna performance.The conformal antenna can meet operating requirements of the system.
