Preface
Smart antennas are antennas with smart signal‐processing algorithms that can electronically reconfigure radiation patterns so that the maximum radiation is formed towards the desired directions while nulls are formed towards interfering sources. It is a key technology for many wireless systems, such as satellite communications, terrestrial mobile communications, inter‐satellite links, radio‐frequency identification, wireless power transmission, wireless local area networks, global navigation satellite systems, radars, remote sensing, and direct broadcast satellite television reception systems. Traditional smart antennas using phased arrays or digital beamforming adaptive arrays are rather complicated in structure, bulky, power hungry, and costly. For commercial applications, it is important to reduce the size, mass, power consumption, and cost of smart antennas. Recent decades have seen lots of progress in research and development in the field of low‐cost smart antennas. It is foreseen that low‐cost smart antennas will be widely implemented in the smart city, fifth‐generation and future generations of mobile communications, smart homes, satellite communication on the move, the Internet of Things, the Internet of Space, and autonomous vehicles.
So far, most books on smart antennas have mainly focused on signal‐processing algorithms, and there are few books specialising in antennas and the radio frequency (RF) hardware of smart antennas. The purpose of this book is to address ...
