A 16-port massive Multiple-Input-Multiple-Output (mMIMO) antenna system featuring a high gain and efciency is proposed for millimeter-wave applications. The antenna system consists of 64 elements with a total size of 17 λo × 2.5λo, concerning the lowest frequency. Each 2× 2 (radiating patch) subarray is designed to operate within the 25.5–29 GHz frequency range. The antenna’s performance in terms of isolation, gain, and efciency has been signifcantly improved by utilizing the proposed unique double and epsilon negative (DNG/ENG) metamaterials. The array elements are positioned on top of a Rogers RT5880 substrate, with ENG metamaterial unit cells interposed in between to mitigate coupling efects. Additionally, the DNG metamaterial refector is positioned at the rear of the antenna to boost the gain. As a result, the metamaterial-based mMIMO antenna ofers lower measured isolation reaching 25 dB, a maximum gain of 20 dBi and an efciency of up to 99%. To further analyze the performance of the MIMO antenna, the diversity gain and enveloped correlation coefcient are discussed in relation to the MIMO parameters.
