Asymptotics of transmit antenna selection: Impact of multiple receive antennas [PDF]
2017 IEEE International Conference on Communications (ICC), 2017 Consider a fading Gaussian MIMO channel with $N_\mathrm{t}$ transmit and $N_\mathrm{r}$ receive antennas. The transmitter selects $L_\mathrm{t}$ antennas corresponding to the strongest channels. For this setup, we study the distribution of the input-output mutual information when $N_\mathrm{t}$ grows large.

Oversampling transmit and receive antenna arrays [PDF]
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010 A dense antenna array architecture is developed to ease the circuit requirements of the radio frequency (RF) front-end in beamforming applications. In the architecture, antennas are spaced more closely than would otherwise be required to exploit the available degrees of freedom.

Communication Modes With Large Intelligent Surfaces in the Near Field
IEEE Access, 2021 This paper proposes a practical method for the definition of communication modes when antennas operate in the near-field region, by realizing ad-hoc beams exploiting the focusing capability of large antennas. The beamspace modeling proposed to define the

Frontiers in Communications and Networks, 2021 A short-range terahertz (THz) wireless transmission in the 300 GHz band is demonstrated using low-profile wavelength-scaled dielectric transmitting and receiving cuboid antennas (DCAs). These dielectric cuboid antennas are made of polytetrafluoroethylene
