论文摘要
提出了一种设计天线激发的技术，以实现正交状态。结果表明，为了获得所有物理量，需要对称天线几何形状才能达到正交性。从对天线对称性的知识中，严格确定了最大数量可实现的正交状态和最小数量的激发它们所需的端口。对于常用点组（矩形，正方形等）总结了状态和端口数量的数量。该理论应用于矩形边缘的示例，其中确定了提供最佳的总主动反射系数的端口位置，即多端口系统中的重要指标。可以根据积分方程轻松地在现有求解器中实现所述技术。
A technique of designing antenna excitation realizing orthogonal states is presented. It is shown that a symmetric antenna geometry is required in order to achieve orthogonality with respect to all physical quantities. A maximal number of achievable orthogonal states and a minimal number of ports required to excite them are rigorously determined from the knowledge of an antenna's symmetries. The number of states and number of ports are summarized for commonly used point groups (a rectangle, a square, etc.). The theory is applied to an example of a rectangular rim where the positions of ports providing the best total active reflection coefficient, an important metric in multi-port systems, are determined. The described technique can easily be implemented in existing solvers based on integral equations.
