Aslan, Y. (author), Roederer, A.G. (author), Fonseca, Nelson J.G. (author), Angeletti, Piero (author), Yarovoy, Alexander (author)Orthogonality in multibeam antennas is revisited. The difference between orthogonal beamforming and zero-forced beamforming is highlighted. The intriguing relation between orthogonality, reciprocity and losses is recapitulated. Different approaches on the design of orthogonal beamforming networks and implementation of zero-forced beamforming...journal article 2021

Aslan, Y. (author), Salman, Salman (author), Puskely, J. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)The performance of space-tapered multi-beam arrays with minimized side lobe levels is statistically evaluated in a line-of-sight propagation environment within a cell sector in terms of the signal-to-interference-plus-noise ratio at the multiple user ends. Comparative analyses are performed to examine the advantages of space-tapered, irregular...conference paper 2019

Salman, Salman (author)Traditionally, antenna design involves optimizing the design parameters such as gain, minimum sidelobe level, scan range, half power beamwidth, for a particular application. Since 5G systems are pushing the boundaries for cellular communications by introducing unique challenges such as multiple beam antennas, beamforming etc. in the field of...master thesis 2018
