论文摘要
对多端口天线研究了对总主动反射系数和实现增益的数值有效描述。完全考虑了物质损失。该描述基于以整个域端口模式为基础表示的运算符，即具有较小尺寸的矩阵。研究最佳性能，并得出有关最佳激发和匹配的条件。还完成了最佳端口放置和最佳进食合成的组合问题的解决方案。数值研究了各种复杂性的四个示例，证明了所提出的方法的优势。最终公式可以使用积分方程求解器轻松在现有的电磁模拟器中实现。
A numerically effective description of the total active reflection coefficient and realized gain are studied for multi-port antennas. Material losses are fully considered. The description is based on operators represented in an entire-domain port-mode basis, i.e., on matrices with favorably small dimensions. Optimal performance is investigated and conditions on optimal excitation and matching are derived. The solution to the combinatorial problem of optimal ports' placement and optimal feeding synthesis is also accomplished. Four examples of various complexity are numerically studied, demonstrating the advantages of the proposed method. The final formulas can easily be implemented in existing electromagnetic simulators using integral equation solver.
