摘　　要：常规印刷对数周期天线(PLPDA)采用同轴电缆馈电,电缆焊接部位在天线顶部。在较高的工作频段(6 GHz或更高),电缆及焊接部位对天线的性能影响较大,这限制了印刷对数周期天线在较高频段的应用。对常规同轴馈电结构的印刷对数周期天线进行了分析,在此基础上提出了一种基于带状线结构的底端馈电印刷对数周期天线,仿真结果表明,天线在6~18 GHz的工作频带内驻波≤2,波束指向及波束宽度保持稳定。The conventional printed log-periodical antenna(PLPDA)is fed by coaxial cable,and the welding point of the cable is at the top side of the antenna.At higher working band(6 GHz or higher),the antenna performance is seriously affected by the cable and the welding point,which limits the application of the PLPDA.In this paper,a PLPDA with bottom feed based on the stripline structure is analyzed.The simulation result shows that,in the frequency band of 6~18 GHz,the antenna standing wave≤2 and the direction&width of wave beam are stable.
