AST SpaceMobile announced this week that its BlueBird 6 satellite successfully deployed its communications array, making it ...

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 ...

AST SpaceMobile has taken a very literal big swing at satellite connectivity, deploying a giant spacecraft meant to talk directly to ordinary smartphones and challenge Starlink’s lead in space-based ...

The Defense Innovation Unit has awarded at least two contracts to build prototype phased array antennas which are capable of connecting with multiple satellites simultaneously. (Lockheed Martin image) ...

Antenna arrays and wideband technologies are at the forefront of modern wireless communication, radar, and electronic warfare systems. Recent advances have focused on optimising beam steering, ...

If you watch old science fiction or military movies — or if you were alive back in the 1960s — you probably know the cliche for a radar antenna is a spinning dish. Although the very first radar ...

In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

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 ...

This article discusses the GALANT adaptively steered antenna array and receiver and demonstrates the test scenarios generated with the GNSS simulator. Exemplary results of different static and dynamic ...
