Wideband dynamic metasurface antenna performance with practical design characteristics
Joseph M. Carlson, Nitish V. Deshpande, Miguel Rodrigo Castellanos +1
Dynamic metasurface antennas (DMA) provide low-power beamforming through reconfigurable radiative slots. Each slot has a tunable component that consumes low power compared to typic…
The Tri-Hybrid MIMO Architecture
Robert W. Heath, Joseph Carlson, Nitish Vikas Deshpande +3
We present an evolution of multiple-input multiple-output (MIMO) wireless communications known as the tri-hybrid MIMO architecture. In this framework, the traditional operations of…
Beamforming with hybrid reconfigurable parasitic antenna arrays
Nitish Vikas Deshpande, Miguel Rodrigo Castellanos, Saeed R. Khosravirad +3
A parasitic reconfigurable antenna array is a low-power approach for beamforming using passive tunable elements. Prior work on reconfigurable antennas in communication theory is ba…
