Typically at lower power than a single antenna, a distributed antenna system (DAS) is commonly deployed for 4G cellular systems in urban areas. A distributed system may even be used in large ...
Historically, testing Controlled Reception Pattern Antenna (CRPA) systems in a laboratory has been a very difficult process — dynamics were limited and test duration was usually short. Often, dynamic ...
Smart antennas have garnered significant attention ... They require sophisticated control systems when the metasurfaces are ...
To enhance antenna flexibility and control, the researchers proposed and ... generation large-capacity and high-security information systems, real-time imaging, and wireless power transfer.
