Project: Electronically Reconfigurable FSS-inspired Transmitarray for Two Dimensional Beamsteering

Acronym: e-Beaming
Main Objective: A novel electronically reconfigurable transmitarray with two-dimensional beamsteering and spatial diversity capabilities is sought to be accomplished with this internal project. This project introduces a new vision on the implementation of spatial diversity with beamsteering capability, by suppressing the typical beamforming networks of antenna phased arrays and replace them by Reconfigurable Transmitarrays. Consequently, the radio frequency components, i.e. RF- chains that compose such systems, will be replaced by a device with the capability to perform two-dimensional beamsteering relying on single antenna source, hence reducing the number of associated RF hardware in comparison with traditional phased array systems. By spatially distributing side-by-side more than one device, spatial diversity with beamsteering is enabled with an estimated reduction of 1:8 in the number of associated RF-chains. This new concept will clearly demonstrate its merit by directly reducing the implementation costs RF-chain components and increasing the energy efficiency, particularly in larger systems.
