Minimal Redundancy Linear Array and Uniform Linear Arrays Beamforming Applications in 5G Smart Devices

Minimum Redundancy Linear Arrays (MRLAs) and Uniform (ULAs) investigation conducted with the possibility of using them in future 5G smart devices. MRLAs are designed to minimize number sensor pairs same spatially correlated delay. It eliminates selected antennas from entire composite antenna array preserves all possible spacing. have attractive features for linear sparse arrays, even if built-in surface is deformed, it works without problems. To our knowledge, not been applied devices so far. In this work, a 7-element ULAs 4-element (same aperture) were used simulation. The Half Power Beamwidth (HPBW) 0.666 Null-to-Null ( ) 1.385 ψ-space. comparison, standard arrays 1.429 3.1416, while 0.801 1.795 respectively. Experimental results show that MLRAs narrower mean beam, much higher sidelobes shallow nulls. Therefore, terms main lobe features, 4- elements an improvement over ULAs.
