An 8-Antenna element MIMO system for compact and thin 5G mobile

Abstract

The most modern technological advancements in several key fields of mobile communication such as massive multiple-input multiple-output (MIMO), millimeter-wave (mmWave) communication with beamforming, Duplex communication, small cells architecture, i.e., femtocell and picocell, and nonorthogonal multiple access (NOMA) based resource sharing schemes, etc., had led to an evolution in imminent next generation of 5G cellular networks. These 5G networks are entitled to provide three classes of broad services to meet the diverse consumers’ needs, i.e., quality of services (QoS) and quality of experience (QoE). One of the key 5G network services is enhanced mobile broadband (eMBB), which has to provide and meets the demands of high data rate-based applications, such as, HD video streaming, smart cities, smart industrial applications, and diverse data rate needs of mobile users. MIMO technology can meet the insatiable demand for high-speed mobile data rate capacities by placing multiple antenna elements closely together at both 5G base stations and 5G end-users through exploiting the multipath rich propagation environment. However, the modern trend in wireless communication of thinner and slimmer designs are making it difficult for the 5G devices to accommodate multiple antennas with avoiding stronger electro-magnetic coupling. It degrades the MIMO system antenna performances. In this thesis, we had developed and studied an 8 element MIMO system for compact and thin 5G user device and analyzed the system performance for various parameters.
