摘　　要：设计了一种连续旋转馈电方式下层叠结构的双单元圆极化微带天线阵。讨论了利用调谐支节优化层叠结构微带天线阻抗带宽的方法,并在此基础上引入连续旋转馈电方式组成了二元微带天线阵。制作并测试了相应的天线阵,结果表明:采用层叠结构可以有效扩展微带天线的阻抗带宽,同时提高了天线增益,连续旋转馈电技术则提高了天线阵的圆极化纯度,测试结果与仿真吻合较好。A circularly polarized stacked microstrip antenna array with the application of sequentially rotated feeding technique is proposed in this paper. Stub-tuning method to optimize the impedance bandwidth is discussed and the sequentially rotated feeding technique is used to build a two element microstrip antenna array. The corresponding array is fabricated and measured. The measured results agree well with the simulation, which indicates that the stacked configuration can effectively enhance the impedance bandwidth and the gain of the microstrip antenna, while the sequentially rotated feeding technique can improve the circularly polarized purity.
