This paper introduces a novel four-port antenna array designed for n260 band operation. specifically addressing challenges like path loss fading and multipath effects commonly encountered in millimeter-wave frequencies in urban settings. The proposed $4 \times 4$ MIMO antenna array operates in the n260 band. offering high gain and a narrow beam. https://www.roneverhart.com/Phi-Mu-Mom-Dad-Embroidered-Button/
