摘要: 在本論文中,我們採用頻域模態匹配法分析週期性不規則接地面對微帶線傳輸特性的影響。在凹入區內,沿傳播方向和垂直傳播方向的電磁場分別用駐波形式的函數和傅立葉積分表示。最後獲得以微帶線上表面電流為未知數的積分方程式,再利用矩量法求解。隨後探討不同幾何及電性參數對此結構第一禁頻帶的通帶/止帶特性之影響。
A mode-matching technique combined with a spectral domain reprsentation is used to study the transmission properties of microstrip lines with a periodically corrugated ground plane. The field components in the corrugated region are expanded by standing wave mode functions in the propagation direction and by a Fourier integral in the transversal direction. Integral equations are formed in terms of the surface currents on the microstrip. Dispersion relation is then obtained by applying method of moments to solve the integral equations. Various geometrical and electrical parameters affecting the passband/stopband characteristics of the first stopband are investigated.
