摘要：

A novel method of decoupling two closely placed antennas is proposed based on tunable metamaterials. The experimental results show that this method has more than 110-dB isolation ratio, frequency and bandwidth reconfigurable ability, and environmental adaptivity. These features are realized by placing multiple varactor-based tunable resonant structures between two antennas within the near-field region and by using artificial intelligent algorithm to optimize the transmission coefficient between the antennas. A case of suppressing mutual coupling between two orthogonally polarized arrays is given to demonstrate the versatility of this method.
