Pattern reconfigurable metamaterial antenna for 5G base station network
Reconfiguration of an antenna’s radiation pattern in a predefined direction is very important for enhancing the performance of communication systems in terms of the quality of service, system security, avoiding interference, and economizing power. Metamaterials, on the other hand, are commonly used …
