Abstract A novel mesh-like isolation rings structure metamaterial is proposed and loaded between two dipole MIMO antennas to enhance the isolation between antennas. The rectangular open resonant ring, the double-layer S-shaped open ring, and the new mesh isolation ring are loaded between the dipole antennas and the S-parameters of the antenna are simulated by HFSS (High Frequency Structure Simulator). The Miniaturized antenna with high isolation is obtained under the same condition that the antenna operating frequency was 2.45 GHz. The simulation experiment verified that the isolation of the dipole antenna loaded with the new mesh isolation ring is 18.87 dB higher than the rectangular open resonator ring and is 4.78 dB higher than the double-layer S-shaped split ring. The mesh-like rings improve the antenna isolation in the experiment.

基于新型网状隔离环的MIMO天线隔离研究

摘要 提出了一种新型网状隔离环结构超材料，并加载在两个偶极子MIMO天线之间，以增强天线之间的隔离度。在偶极天线之间加载矩形开环谐振环、双层S形开环和新型网状隔离环，并通过HFSS（高频结构模拟器）模拟天线的S参数。在天线工作频率为2.45 GHz的相同条件下，获得了高隔离度的小型化天线。仿真实验验证了加载新型网状隔离环的偶极子天线的隔离度比矩形开口谐振环高18.87 dB，比双层S形开口环高4.78 dB。网状环提高了实验中的天线隔离度。
