摘要: 本論文描述一個嚴格的數值方法,用以特性分析共平面波導之不連續面.在 論文中我們先推導由邊界條件所得的積分方程式,再使用動差法去求在共 平面波導槽上的電磁場分布,以及由不連續面所造成的反射係數.而由所求 的反射係數我們便能將不連續面電路化.在整個分析過程中,表面波以及放 射的效應皆被嚴格考慮.在論文中有兩種型式的不連續面被研究;包括有開 路和短路不連續面.更進一步,我們也研究共平面波導金屬背的高度所造成 的影響.最後,為了確定數值結果的正確性,我們將所得結果和一些文獻比 較,發現是恰當的. This thesis describes a rigorous numerical approach for characterizing coplanar waveguide discontinuities. The method in the thesis employs the moment method to find the unknown electric field distribution on the slot apertures and subsequently the scattering parameter of the discontinuities. In this approach coplanar waveguide open-end and short-end discontinuities are investigated by the spectral domain integral equation method. Surface wave and radiation effects are properly included in the analysis method. The numerical results obtained are validated by comparing with experimental data and numerical data in the literature.
