Large-scale multibeam phased array systems suffer from interbeam interference (IBI) that should be canceled either in the analog or digital domain. In wideband systems such as fifth generation (5G), interference rejection over a wide bandwidth is cha

The sixth generation (6G) communications is expected to involve the use of the sub-Terahertz. Electromagnetic waves in this band is vulnerable to blockages by physical obstacles, besides the severe limitation of coverage area compared to in conventio

This article proposes a systematic approach for stacking uniform linear arrays (ULAs) of different sizes to reduce sidelobes and form nulls to the radiated beam pattern. In sidelobe reduction, the nulls and sidelobes of the vertically stacked ULAs ar
