Design and performance analysis of MIMO antennas for 5G and future communications

Abstract

MIMO (Multiple-Input, Multiple-Output) technique is considered a newlinecrucial and promising aspect of future wireless communication systems. The newlineusage of MIMO technology significantly improves the data rate, transfer newlinespeed, channel capacity, as well as throughput of systems for wireless newlinecommunication. MIMO antennas use multiple antennas at both the newlinetransmission and reception ends. As technology advances, next wireless newlinecommunication services will need enhanced data speeds. Developing an newlineantenna for a MIMO system that minimizes mutual interaction among its newlinecomponents to enhance transmission speeds and capacity, while facing newlinevarious constraints. The objective is to create a miniature planar MIMO newlineantenna supporting 5G and next generation wireless communications that newlinedemonstrates superior return loss. The main challenge in planar MIMO newlineantenna development is mutual coupling, which may be alleviated using newlinetactics including as decoupling networks, defective ground structures, newlineparasitic elements, and neutralization methods. newlineThe primary performance metrics of the antenna system encompass newlineS-parameters, current distribution, gain, radiating efficiency, radiation newlinecharacteristics, and MIMO diversity evaluation metrics including Envelope newlineCorrelation Coefficient (ECC), Total Active Reflection Coefficient (TARC), newlineDiversity Gain (DG), and Channel Capacity Loss (CCL). newline
