Frequency-selective beamforming and single-shot beam training with dynamic metasurface antennas
Nitish Vikas Deshpande, Joseph Carlson, Miguel R. Castellanos +1
Dynamic metasurface antennas (DMAs) beamform through low-powered components that enable reconfiguration of each radiating element. Previous research on a single-user multiple-input…
Towards 6G MIMO: Massive Spatial Multiplexing, Dense Arrays, and Interplay Between Electromagnetics and Processing
Emil Björnson, Chan-Byoung Chae, Robert W. Heath +7
The increasing demand for wireless data transfer has been the driving force behind the widespread adoption of Massive MIMO (multiple-input multiple-output) technology in 5G. The ne…
Electromagnetic manifold characterization of antenna arrays
Miguel R. Castellanos, Robert W. Heath
Antenna behaviors such as mutual coupling, near-field propagation, and polarization cannot be neglected in signal and channel models for wireless communication. We present an elect…
A generalization of the achievable rate of a MISO system using Bode-Fano wideband matching theory
Nitish Deshpande, Miguel R. Castellanos, Saeed R. Khosravirad +3
Impedance-matching networks affect power transfer from the radio frequency (RF) chains to the antennas. Their design impacts the signal to noise ratio (SNR) and the achievable rate…
