Abstract

The global electronics industry is one of the most innovation-driven and technology-intensive sectors in the contemporary world economy. From semiconductors to end products, complex transnational production and value-generating activities have integrated diverse macro-regions and national economies worldwide into the "interconnected worlds" of global electronics. This book argues that the current era of interconnected worlds started in the early 1990s when electronics production moved from systems dominated by lead firms in the United States, Western Europe, and Japan towards increasingly globalized and cross-macro-regional electronics manufacturing centered in East Asia. By the 2010s, this co-evolution of production network complexity transformed global electronics, through which lead firms from South Korea, Taiwan, and China integrated East Asia into the interconnected worlds of electronics production across the globe. Drawing on literature on the electronics industry, new empirical material comprising custom datasets, and extensive personal interviews, this book examines through a "network" approach the co-evolution of globalized electronics production centered in East Asia across different national economies and sub-national regions. With comprehensive analysis up to 2021, Yeung analyzes the geographical configurations ("where"), organizational strategies ("how"), and causal drivers ("why") of global production networks, setting a definitive benchmark into the dynamic transformations in global electronics and other globalized industries. The book will serve as a crucial resource for academic and policy research, offering a conceptual, empirically driven grounding in the theory of these networks that has become highly influential across the social sciences.

Abstract

With the rapid evolution of the wireless communications, fifth-generation (5G) communication has received much attention from both academia and industry, with many reported efforts and research outputs and significant improvements in different aspects, such as data rate speed and resolution, mobility, latency, etc. In some countries, the commercialization of 5G communication has already started as well as initial research of beyond technologies such as 6G.MIMO technology with multiple antennas is a promising technology to obtain the requirements of 5G/6G communications. It can significantly enhance the system capacity and resist multipath fading, and has become a hot spot in the field of wireless communications. This technology is a key component and probably the most established to truly reach the promised transfer data rates of future communication systems. In MIMO systems, multiple antennas are deployed at both the transmitter and receiver sides. The greater number of antennas can make the system more resistant to intentional jamming and interference. Massive MIMO with an especially high number of antennas can reduce energy consumption by targeting signals to individual users utilizing beamforming.Apart from sub-6 GHz frequency bands, 5G/6G devices are also expected to cover millimeter-wave (mmWave) and terahertz (THz) spectra. However, moving to higher bands will bring new challenges and will certainly require careful consideration of the antenna design for smart devices. Compact antennas arranged as conformal, planar, and linear arrays can be employed at different portions of base stations and user equipment to form phased arrays with high gain and directional radiation beams. The objective of this Special Issue is to cover all aspects of antenna designs used in existing or future wireless communication systems. The aim is to highlight recent advances, current trends, and possible future developments of 5G/6G antennas.
