The text begins by covering the fundamental concepts and new advances in the field of antenna theory, antenna hardware, and propagation. It further explains the designing of metamaterials microstrip patch antennas for medical applications, photonic crystals of millimeter wave signals for 5G communications, dual-band miniaturized circular antennas for wireless networks, and ultra-thin compact flexible antennas for wearable applications. In recent years, antenna design has gotten a lot of attention. This is due to a surge in interest in a variety of applications, ranging from IoT to low‑frequency long‑range applications to high‑frequency mmWave 5G mobile technology. Future phones and base stations will need multimode antenna technology that is both energy efficient and can function in the millimeter wave band in conjunction with legacy 4G and sub‑6 GHz 5G. Antennas should be small in size, but they must meet technical criteria such as greater power, wider bandwidth, higher gain, and insensitivity to human users’ hand‑held influence.

Radar array design aims at shaping a specific transmit/receive beampattern through optimizing array geometry, transmit waveform, and transmit/receive weight vectors. It is a hot topic among the scientific and industrial communities due to the advent of modern digital arrays with multiple digital transmit and receive channels, arbitrary digital waveform generators, and solid-state transmitters. The radar array beampattern is a critical performance metric, and there has been a proliferation of techniques for radar array design exploiting the mathematical results drawn from optimisation theory. This book provides an overview of radar beampattern synthesis based on optimised array design. Innovative and sophisticated instruments from optimization theory, such as alternating direction method of multipliers (ADMM), coordinate descent technique, semidefinite relaxation, rank-one matrix decomposition, Lagrange duality theory, fractional programming, convex approximation, Pareto optimization, and Machine Learning (ML) are framed in the context of radar array design.

Make a stand-alone weather data recorder to collect air pressure, air temperature, and humidity data using only an Arduino, SD-card, LCD display, and solar power. Start with that base data. Then easily extend your project to include more such as an XBee radio and sensors for air quality and radiation. Chunyin has years of experience as a researcher in meteorology and oceanography. The projects in this book are based on actual deployable weather data recorders used for collegiate and professional applications. These weather recorders were deployed over coastal water and lands including the Arctic. And you can deploy your own finished model in your backyard, school yard, roof top, or even in the field to collect data at programmed intervals. For meteorological hobbyists, Makers, and students interested in learning how to collect and analyze data with low-cost hardware.

Grasp the future of wireless communication with this groundbreaking introduction. Research and development are already underway on the sixth generation (6G) of wireless communication technology. The new requirements of 6G that arise from challenging new use cases render physical layer waveforms such as CDMA and OFDM inadequate. The OTFS waveform answers these new requirements, and recent research suggests it will play a decisive role in the future of wireless communication. OTFS Modulation – Theory and Applications provides the first ever foundational textbook that introduces this growing, state-of-the-art, field of research from first principles. Beginning with a thorough discussion of the fundamental principles of OTFS, both physical and theoretical, it rigorously situates OTFS modulation in a mathematical framework analogous to more familiar waveforms. The result is a groundbreaking contribution to communication theory and a must-have volume for wireless communication researchers.
