WASHINGTON — The U.S. Space Force is launching a new competition for mobile satellite-control antennas, formally restarting a program it canceled after abandoning a $1.7 billion contract with ...

The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion ...

A newly designed foldable phased-array transmitter can help make satellites lightweight, smaller, and cost-efficient to launch, report scientists at Tokyo Tech. The transmitter is made of stacked ...

Electrical engineers have developed the world's most complex 'phased array' -- or radio frequency integrated circuit. This advance is expected to find its way into US defense satellite communication ...

Phased array technology is far from new. Phased-array antennas have been used for decades in a variety of military applications. Now, however, their use in 5G systems in the Band 2 frequency range is ...

Light detection and ranging (LiDAR) is of central importance for modern artificial intelligence (AI) assisted automated intelligent optical devices. Silicon-based optical phased arrays (OPAs) have ...

Beamforming, based on multiple-input, multiple-output (MIMO) phased-array antennas, looks to make up a component part of the overall 5G cellular technology. While phased-arrays have been the basis of ...

Phased array antennas rely on precise control of amplitude and phase at each element to steer beams and shape radiation patterns without mechanical movement. Calibration adjusts for imperfections ...
