Textbook in PDF format The book proposes a smart antenna structure to overcome airspace congestion, which improves the overall wireless performance and deployment cost. With the combination of practical know-how and theoretical estimation, this book provides insight on how the modern smart antenna techniques that support most cutting-edge wireless technology can be adopted into the existing infrastructure whilst minimising the distraction to the existing system. This bookis suitable for industrial and academic researchers, practising engineers within the field of smart antennae, and wireless infrastructure designers and developers
