耦合渐变槽线天线及其和差波束的矩量法分析

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（ＭｏＭ）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重的，本文集中讨论简化ＭｏＭ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

Method of Moments Analysis for Sum/Difference Beams of Coupled Tapered Slot-Line Antennas

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.
