This book discusses disruptively innovative antenna technologies that can break through the fundamental constraints of conventional fixed-position antenna technologies. The authors show how this technology can enable the full exploitation of wireless channel spatial variation at transceivers with flexible position and rotation antennas, called six-dimensional movable antennas (6DMAs). The book studies challenges in 6DMA-enhanced wireless networks by unveiling associated new channel models, hardware implementations and architectures, and practical position/rotation constraints, as well as various appealing applications in wireless networks. The book investigates innovative signal processing and communication methods for 6DMA to reap its high-performance gains under practical environmental conditions. The authors propose two novel 6DMA channel estimation algorithms and six antenna position and rotation optimization algorithms. The authors are senior and experienced researchers in the areas of advanced antenna technology, 6G, and wireless network.Presents six-dimensional movable antenna (6DMA) technology for 6G and beyond wireless research;Studies design issues and challenges in 6DMA-enhanced wireless networks;Investigates signal processing and communication methods for 6DMA to reap its high-performance gains.
