MIMO Antennas for Wireless Communication

The desired objective of this book is to investigate diversity and mutual coupling effects on MIMO antenna designs for WLAN/WiMAX/LTE applications, controlled with diversity and ground modification techniques including equivalent circuit diagrams. Diversity techniques in MIMO antennas leading to the performance improvement ratings are demonstrated and deliberated. The book contributes towards the development of 2:1 VSWR MIMO antennas with diversity techniques for indoor/outdoor applications for high data rate, QOS, and SNR. The improved MIMO antenna structures are investigated and presented in this book including part of massive MIMO to provide the important aspects of emerging technology. Aimed at researchers, professionals and graduate students in electrical engineering, electromagnetics, communications and signal processing including antenna theory and design, smart antennas, communication systems, this book: - Investigates real time MIMO antenna designs for WLAN/WiMAX/LTE applications. - Covers effects of ECC, MEG, TARC, and equivalent circuit. - Addresses the coupling and diversity aspects of antenna design problem for MIMO systems. - Focus on the MIMO antenna designs for the real time applications. - Exclusive chapter on 5G Massive MIMO along with case studies throughout the book.
