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), Roederer, A.G. (author), Yarovoy, Alexander (author)The system effects and trade-offs of varying the minimal angular separation among multiple simultaneous co-frequency users are investigated for a high-capacity multibeam communication scenario. Through the statistical system simulations, it is demonstrated that the optimal (non-zero) value of the required separation depends on the base station...conference paper 2020
