摘　　要：结合微带天线和偶极子天线的优势,设计了一种低剖面的宽带贴片偶极子微带天线单元。通过仿真与优化,扩展了频带带宽。在C频段的电压驻波比小于2、相对带宽达到80%。同时,天线单元的增益在频带内均大于5.5 d B,频带内辐射效率大于92%。天线单元可用于共形天线阵列的设计,有良好的应用前景。A low-profile wideband patch microstrip dipole antenna element is designed combining the advantages of the microstrip antenna and the dipole antenna. The antenna bandwidth is extended via simulation and optimization. The VSWR is less than 2, and the relative bandwidth reaches 80% at C band. At the same time, the antenna gain is more than 5.5 dB, and the radiation efficiency is more than 92% within the frequency band. This antenna element can be used for the design of the conformal antenna array, which has favorable application prospects.
