    Design and Applications Of Massive Mimo Antenna With Metasurface For 5g Wireless Communications System
    (2026) Abinet Oche
    The increasing demands for network expansion require Multiple-Input Multiple-Output (MIMO) technology which needs Multiple-Input Multiple-Output (MIMO) technology that can deploy extensive antenna systems. The study investigated the complete characteristics of a large MIMO antenna together with its adaptable Meta surface which supports innovative 5G wireless communication technology. The proposed design uses Meta materials to achieve electromagnetic control which solves three major problems such as mutual coupling, bandwidth constraints, and ineffective beam formation that affect standard MIMO systems. A trapezoidal patch antenna array was developed and optimized to function in the sub-6 GHz frequency range specifically at 3.5 GHz which serves as a vital 5G access network frequency. The Meta surface augmented design achieves significant performance improvements over traditional patch arrays in three key areas design delivers notable gains in isolation, directivity, and gain, which full wave simulations demonstrate through comprehensive testing.
