摘　　要：研究了共形于小曲率半径圆柱体的蝶形微带天线,首先计算了平面蝶形微带天线,然后对不同圆柱半径下天线的反射损耗和方向图进行了仿真,与文献结果进行了比较,验证了程序的有效性.表明,当圆柱半径较小于一个波长时,随着圆柱半径的减小,天线谐振频率有所下降,阻抗带宽有所减小,而且方向图有较大变化.Bowtie microstrip antenna conformal to cylinders with small curvature radius is studied. First the planar bowtie microstrip antenna is analyzed and compared with the experimental results to verify the program validity. Then, the simulation of return loss and radiation patterns of different curvature radius is presented. It is shown that, when the cylinder radius is decreased, the resonant frequency is lowered, the bandwidth reduced, and the radiation patterns significantly changed.
