We propose a beamforming method based on curved conformal metasurfaces fed by a slot-coupled patch antenna array. This conformal metasurface comprises five distinct planar metasurface subarrays and ...

Millimeter-wave (mmWave) and sub-Terahertz (THz) communications are compelling as an enabler for next-generation wireless networks. In this paper, we study mmWave and sub-THz systems with ...

Polarization Polarization is used to enhance the performance of beamforming by providing more precise control over the direction of the beam and creating a narrower beam with higher signal strength.

Explore second-generation beamforming and its advanced signal processing algorithms that enhance network efficiency.

This paper proposes variable subarray beamforming (VS-BF) for MIMO transmission in LEO satellite feeder links, which reduces transmission quality degradation due to PAPR and improves capacity.

In this paper, we address the problem of constant-beamwidth beamforming using nonuniform planar arrays. We propose two techniques for designing planar beamformers that can maintain different ...

DFT-based precoders match in this case the channel structure providing a good beamforming gain. Note that the column vectors in a DFT codebook generate a grid of beams (GoB) that can be used to span ...

Having less hardware is an advantage from the cost and power perspectives, but without an all-digital beamforming design, some flexibility in terms of steering resolution is sacrificed in the RF ...
