Scalability of MIMO Antennas: Assessing Gain and HPBW for Different Antenna Element Configurations

Jurnal Rekayasa Elektrika
The design of Massive MIMO Antennas presents challenges due to their large size, which can impede the design process. Additionally, the arrangement of multiple antenna elements in Massive MIMO Antennas poses a challenge, as it surpasses the capabilities ...

Intelligent Surface-Aided Transmitter Architectures for Millimeter-Wave Ultra Massive MIMO Systems

IEEE Open Journal of the Communications Society, 2021
In this article, we study two novel massive multiple-input multiple-output (MIMO) transmitter architectures for millimeter wave (mmWave) communications which comprise few active antennas, each equipped with a dedicated radio frequency (RF) chain, that ...

Personal area networks with line-of-sight MIMO operation

, 2006
In this paper, the results of an on-body, line-of-sight (LOS), multiple-input, multiple-output (MIMO) channel sounding investigation are reported. Transmission takes place between on-body antennas and a uniform linear array, positioned at close range and

An antenna solution for MIMO channels: the switched parasitic antenna [PDF]

12th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications. PIMRC 2001. Proceedings (Cat. No.01TH8598), 2002
We investigate the switched parasitic antenna (SPA), which is a novel technique for electronically directing the radiation pattern in a MIMO system. The correlation between the received signal modes is shown to be sufficiently low to yield a diversity gain.

Generalised pre-coding aided spatial modulation [PDF]

, 2013
A new Multiple Input Multiple Output (MIMO) transmission scheme termed as Generalised Pre-coding aided Spatial Modulation (GPSM) is proposed, where the key idea is that a particular subset of receive antennas is activated and the activation pattern ...
