论文摘要
提出了一种特征模式（CM）方法，该方法依赖于表面积分方程的全局多轨道公式（MTF），以计算具有有限的介质底物和接地平面的微带贴片天线的模式和谐振频率。与电场和poggio-miller-chang-harrington-wu-tsai积分方程的耦合公式相比，全局MTF允许更直接实现子结构CM方法。这是通过代表基材和接地平面上的电磁场的耦合来实现的，该型数绿色函数矩阵的形式产生了更紧凑的广义特征值方程。由此产生的子结构CM方法避免了对多层绿色函数的繁琐计算（与依赖混合电位积分方程的CM方法不同）和底物的体积离散化（与CM方法不同（与CM方法不同，CM方法依赖于体积的积分方程），并且数值是一种可靠的行为来预测型号的行为，以预测MODN的行为，以实现MODN的行为，以实现MODN的方法。微带天线。
A characteristic mode (CM) method that relies on a global multi-trace formulation (MTF) of surface integral equations is proposed to compute the modes and the resonance frequencies of microstrip patch antennas with finite dielectric substrates and ground planes. Compared to the coupled formulation of electric field and Poggio-Miller-Chang-Harrington-Wu-Tsai integral equations, global MTF allows for more direct implementation of a sub-structure CM method. This is achieved by representing the coupling of the electromagnetic fields on the substrate and ground plane in the form of a numerical Green function matrix, which yields a more compact generalized eigenvalue equation. The resulting sub-structure CM method avoids the cumbersome computation of the multilayered medium Green function (unlike the CM methods that rely on mixed-potential integral equations) and the volumetric discretization of the substrate (unlike the CM methods that rely on volume-surface integral equations), and numerical results show that it is a reliable and accurate approach to predicting the modal behavior of electromagnetic fields on practical microstrip antennas.
