In this paper, a new metasurface-based antenna configuration for 5 G wireless network has been presented. This configuration is designed for wireless communications in the 28 GHz frequency band. It consists of a $4 \times 5$ matrix of absorbing split-ring resonator (SRR) cells. The objective is to analyze the effect of the presence of a metasurface layer placed at a precisely defined distance under the patch antenna. The parametric study of this distance was carried out in order to optimize the performance of this proposed antenna. The simulation results using the CST simulation software show that in the presence of the metasurface, the gain increases to a maximum value of 8.5 dBi. This improvement shows the interest of the presence of absorbing split-ring resonator cells for optimizing patch antenna efficiency for 5G wireless applications.
