摘　　要：该文设计了一种圆柱体表面共形的全向微带缝隙天线阵。该天线采用低剖面缝隙天线作为阵列单元,利于实现共形;采用H形缝隙对天线单元进行小型化设计,以实现较小间距的组阵,从而获得较好的方向图不圆度。对提出的天线进行仿真设计及优化,获得了5.35%的相对带宽,仿真增益达到4.2dBi,H面不圆度≤1.5dB。A cylindrical conformal antenna array is designed in this paper with omnidirectional radiation pattern using microstrip slot antenna elements.Microstrip slot antenna with low profile is used for achieving the conformal array and H shaped slot is applied to reduce antenna element＇s size for well un-roundness in omnidirectional pattern with small element＇s spaces.With optimized design of the proposed antenna,the simulated relative bandwidth is 5.35% with the antenna gain of 4.2dBi and un-roundness in H-plane pattern of less than 1.5dB.
