A New Adaptive Near Field Isolation Method Based on Controllable Metamaterial

天线之间的隔离度在许多无线通讯系统中都有要求。在诸如多天线的MIMO 系统、同频双工等等众多实际工程中，天线的隔离度直接决定了工作设备的性能。 而这些天线往往处于彼此的近场，而近场隔离相对于远场有更高的难度。现有的 提高隔离度的方法普遍只能达到30dB到50dB左右的隔离度，并且均是静态方 法。这在实际应用中往往无法满足越来越高的性能和功能要求。 本文提出了一种基于可控超材料和人工智能算法的自适应近场隔离方法。首 先给出了基本的数学模型，并证明该方法的合理性。为了检验理论的正确性，根 据理论模型加工了相应的超材料和天线系统并在暗室中搭建了相应的实验环境、 编写了基于遗传算法的人...The isolation between antennas is required in many wireless communication systems. In many practical projects, such as the MIMO system with multiple antennas, the same frequency duplex and so on, the isolation of the antenna directly determines the performance of the equipment. These are often in the near field antenna near-field isolation of each other, with respect to the far field has a...学位：工程硕士院系专业：物理科学与技术学院_工程硕士(电子与通信工程)学号：3312013115285
