Beamfocusing Capabilities of a Uniform Linear Array in the Holographic Regime
Xavier Mestre, Adrian Agustin
The use of multiantenna technologies in the near field offers the possibility of focusing the energy in spatial regions rather than just in angle. The objective of this paper is to…
Exploiting Multiple Polarizations in Extra Large Holographic MIMO
Adrian Agustin, Xavier Mestre
The proliferation of large multi-antenna configurations operating in high frequency bands has recently challenged the conventional far-field, rich-scattering paradigm of wireless c…
Available Degrees of Spatial Multiplexing of a Uniform Linear Array with Multiple Polarizations: A Holographic Perspective
Xavier Mestre, Adrian Agustin, David Sarda
The capabilities of multi-antenna technology have recently been significantly enhanced by the proliferation of extra large array architectures. The high dimensionality of these sys…
Near-Field Beamfocusing with Polarized Antennas
Adrian Agustin, Xavier Mestre
One of the most relevant challenges in future 6G wireless networks is how to support a massive spatial multiplexing of a large number of user terminals. Recently, extremely large a…
