This book presents up-to-date information about WLAN antenna designs for students, researchers, and professionals who want to design radiating systems to be deployed for practical coverage. The book primarily focuses on pattern diversity antennas. Pattern diversity antennas are very vital in wireless communication. High correlation between multiple signals can result in low data throughput which can be solved by using antennas with pattern diversity. Beam scanning antennas and their variants are also described in detail. Pattern diversity antenna systems with multiport feeds are also comprehensively discussed in this book. For a multiport system to maintain a reasonable link budget, equal antenna gains are preferred for the required antenna coverage. The book further describes the latest techniques to enhance and equalize the antenna gain within a compact radiating system. With increasing demand for faster connectivity with minimum path loss, the demand for high-gain antennas is rapidly increasing. Thereby a detailed discussion on gain enhancement with the latest high-gain antenna designs is requisite while describing WLAN antennas. Some antenna designs discussed in the book are based on additive manufacturing for their design and fabrication. Additive manufacturing is a much sought-after technology today that allows rapid development of antennas at an affordable cost. Many recent WLAN antennas make use of this technology to develop versatile antenna designs. Finally, the book includes a section on wide-band antenna designs. Antenna designs that reduce the scanning loss are also discussed.

"This is the first textbook that contains a holistic treatment of traditional antennas mounted on masts (Line-of-Sight antenna systems) and small antennas used on modern wireless devices that are subject to signal variations (fading) due to multipath propagation. The focus is on characterization and describing classical antennas by modern complex vector theory, thereby linking together many disciplines, such as electromagnetic theory, classical antenna theory, wave propagation, and antenna system performance."--Back cover.

Transforming the way we live, work, and engage with our environment, 5G and beyond technologies will provide much higher bandwidth and connectivity to billions of devices. This brings enormous opportunities but of course the widespread deployment of these technologies faces challenges, including the need for reliable connectivity, a diverse range of bandwidths, dynamic spectrum sharing, channel modelling and wave propagation for ultra-dense wireless networks, as well as price pressures. The choice of an antenna system will also be a critical component of all node end devices and will present several design challenges such as size, purpose, shape and placement. In this edited book, the authors bring new approaches for exploiting challenging propagation channels and the development of efficient, cost-effective, scalable, and reliable antenna systems and solutions, as well as future perspectives.

This is a modern textbook. The formulas for the radiation fields from different antennas are expressed in a compact and unified way by means of the direct vector integral relations between fields and currents. Thereby the formulas become easy to apply and interpret. The Moment Method is introduced as a basic principle in field theory, and it is used together with the equivalence principle to derive the classical formulas in antenna theory. The book comes with a CD-ROM. This contains the over 50 computer programs which have been used to produce the results in all the graphs in the book. These computer programs are referred to as Mathcad Documents. They can be run without buying extra software, and without having any previous knowledge of Mathcad. The Mathcad Documents provided can be used for initial designs of dipole, slot, microstrip, horn, reflector and array antennas (by classical formulas). Good initial designs will reduce the time and cost needed for fine tuning of performance with more advanced CAD software. The Mathcad Documents can also be used to validate other software. The CD-ROM also contains HTML slides of all the material in the book.
