Active tile for room-size UWB 2-D communication

This paper presents a practical scheme to enhance a two-dimensional communication (2DC) system to the entire floor of a room. The 2DC uses a waveguide sheet as a physical communication medium. Covering an entire room floor with a large single piece of sheet is impractical in terms of fabrication, delivery, and installation. An alternative scheme, in which the floor is covered with waveguide sheet tiles, has been proposed. This paper proposes an active tile system as a specific implementation of the scheme. A circuit configuration is presented and the feasibility is demonstrated through measurements on an experimental system.
