Multifunctional antennas are a comparatively new area of antenna research. Cognitive radio (CR) in software-defined radio (SDR) technology and MIMO technology are some of the new technologies employing these antennas, which include integration of multiple antennas with narrowband and ultrawideband (UWB) characteristics. Designing of UWB antennas for CR and MIMO technology is another area of vibrant research. This book is an attempt to assimilate works done by different researchers and authors over the last few years on antennas that can perform multiple antenna functionalities. Chapter 1 focuses on an overall introduction to the UWB system, including an historical perspective through to the most recent applications of UWB technology. Chapter 2 deals with the discussion on the design and development of UWB antennas and the discussion on various classes of UWB antenna designs proposed by research groups over the last two decades. Chapter 3 deals with techniques of designing UWB antennas with frequency stop or frequency notch characteristics. Several antenna designs are described which provide frequency notch response and the techniques involved. Chapter 4 deals with the design and development of antennas capable of performing multiple antenna functionalities. As CR in SDR technology is the major application of these antennas, a section focuses exclusively on antenna requirements for SDR and CR technologies. Various arts and techniques of designing multifunctional antennas and their advantages are thoroughly discussed. Chapter 5 deals with arts and techniques of design and the realization of reconfigurable UWB antenna design with a clear focus on recent and upcoming technological requirements. A section on a recent technique of designing dual reconfigurable printed antenna, which can work as a tunable notched UWB antenna and reconfigurable narrowband antenna, is discussed. In addition, filter integrated UWB reconfigurable antenna, popularly known as reconfigurable filtenna, is also discussed. Fundamental concepts and physical insight on the design principles and contemporary contributions by various researchers are also highlighted. The last chapter, Chapter 6, focuses on MIMO antennas for UWB applications. As MIMO systems deal with multiple antennas installed in a common platform, their performance metrics in terms of additional parameters such as envelope correlation coefficient (ECC), diversity gain (DG), mean effective gain (MEG), total active reflection coefficient (TARC), etc. are also discussed. After a brief overview on MIMO antenna parameters, design of UWB-based MIMO antennas is thoroughly discussed. In addition, the chapter includes two sections focusing on frequency notched MIMO antenna design and isolation-enhancement techniques in MIMO antennas.
With Multi-Functional Ultra Wideband Antennas: Trends, Techniques and Applications, antenna engineers, communication system engineers, graduate students, academic/industry researchers will gain a thorough knowledge on design of such antennas with clear physical insight and understanding.
