摘要
本文阐述一种新型渐变槽线天线 (TSA)结构 ,耦合渐变槽线天线 CTSA。单片的 CTSA除可降低副瓣电平 ,提高增益 ,改善 E面 H面波束的对称外 ,还可通过与之配合的平面印刷奇偶模双工器馈电 ,同时实现和差波束。本文应用空间域矩量法 (Mo M)建立了分析各种 TSA结构的数值模型 ;该方法在没有介质基片的情况下是严格的。本文集中讨论简化 Mo M中阻抗矩阵积分运算的各种技术 ,有效地减小了计算量 ,并获得较高的精度。计算结果与文献结果对比正确。对
The Coupled Taper Slot line Antenna (CTSA) possesses the advantages of equa lized beam in both E and H planes, and reduced side lobes in H plane. With proper feed network, CTSA can radiate linear polarized sum and difference beams respectively. Although several methods have been employed to analyze a single TSA, it is lacking in theoretical analysis. In this article, radiation patterns are analyzed from a reaction integral equation by using MoM for a CTSA without dielectric substrate, the computational results are presented and discussed.
