本文介绍一种解析设计方法,它能在存在外部互耦的条件下,对给定的口径分布和输入阻抗,确定一个共线裂缝阵中每个缝的长度和带线相对于每个缝的倾角。这种理论是建立盒式带线的TEM模电流与裂缝电压间关系的Stevenson近似法的推广,同时应用几何绕射理论(GTD)来表示裂缝单元之间的外部耦合。于是引入了一种将谐振缝长度限制在实际值的最新方法。为证实该理论而设计的一个阵给出了良好的结果。
This paper presents an analytical design method that determines the length of each seam in a collinear fracture array and the line relative to each seam for a given caliber distribution and input impedance in the presence of external mutual coupling inclination. This theory is a generalization of the Stevenson approximation to establish the relationship between the TEM mode current and the fracture voltage of a cassette tape. The theory of geometry diffraction (GTD) is used to represent the external coupling between fracture cells. Thus a new method of limiting the length of the resonant slit to the actual value was introduced. A matrix designed to prove this theory gives good results.
