“…The orthogonal beam space was divided into orthogonal channels, each composed of a few (2 or 3) orthogonal beams. In [101], considering the intrinsic limitations of the orthogonal lossless networks (i.e. maximal number of beams is equal to the number of radiating elements, with an imposed relation between them), the possibility of using dissipative (or lossy) networks with more beams than the elements was investigated.…”

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 strategies are shown with various examples from the antenna-research-oriented literature. The use of orthogonal and zero-forced beamforming is discussed from the communication system perspective with relevant studies from diverse disciplines. Some of the future research challenges and potential benefits are outlined for the next generation satellite and cellular communication applications.

“…Since sixteen beams are necessary and there is only eight rows of radiating elements, half of the steering network outputs would be loaded, thus, there would be a loss of 3 dB in transmission. An example of the design and realization of these lossy networks is shown in [64].…”
