摘　　要：为了满足X频段机载雷达天线的指标要求,使得矩形平面天线与柱面共形,通过并联侧馈方式进行馈电;在微带共形阵天线的相关理论基础上,阵元采用介电常数2.2,厚度为0.5 mm的介质基板;通过HFSS12对微带共形阵天线进行仿真设计并优化;实验结果表明,在X波段内实现了方位面的全向扫描,实测阻抗带宽为9.80～10.20 GHz,最大增益可达10 dB,全向辐射性能稳定,满足了指标要求.In order to meet the X-- band radar antenna airborne target, so that rectangular plane and cylindrical conformal antenna, con dueted in parallel side--fed feeding mode. In the basis of relevant theories conformal microstrip antenna array on the array element using a dielectric constant 2.2, dielectric substrate thickness of 0.5 mm. By HFSS12 microstrip conformal array antenna simulation and design opti- mization is realized. The results show that in the X--band to achieve the azimuth plane of omni--directional scanning, the measured imped- ance bandwidth 9.80--10.20 GHz, maximum gain up to 10 dB, omnidirectional performance and stability, the indications meet the require- ments.
