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...
