| 摘 要： | 为了拓展渐变槽线天线的工作频带,提出一种采用共面波导新型馈电结构的双面印刷对跖型渐变槽线天线.基于对渐变槽线天线之宽频带特性受限于现有馈电方式的分析,改用蚀刻于背板的共面波导至双面印刷对跖渐变槽线的行波式转接.其仿真和实验结果一致表明:该馈电方式使天线的阻抗具有高通频响特性,且保持较好的辐射方向性图,在3 GHz以上的...

| Abstract: | In order to broaden the bandwidth of a tapered slotline antenna(TSA),a bilateral tapered slot-line antenna(BTSA) with a new feeding structure of coplanar waveguide(CPW) is developed.Based on the fact that the bandwidth limitation of TSA mainly depends on its feeding structure,an improved CPW-based feed structure etched on the backboard of the BTSA is adopted to perform traveling-wave transition.Both the simulation results and measurement data verify that the proposed feeding structure results in high-pass ... |
