Arralis announces new Ka-band phased array aircraft antennas


Arralis, world leaders in building millimetre wave technologies and products - seen as the future of precision radar and satellite communications - today announced their new Ka band analogue phase shifters that enable true electronically steerable, low profile antenna to be offered to commercial and defence aircraft market .

Senior fleet operators, network providers and platform users at the recent APSAT Conference in Jakarta agreed that satellite antennas have been the weak point for satellite broadband. Until now, they blame a lack of innovation for ongoing issues with cost, size, poor aerodynamics, insufficient throughput and single satellite operation. The Arralis compact, lightweight and aerodynamic Ka band phased array antennas, that need no stabilisation requirements, are 400% smaller than their Ku band counterparts and are made specifically with airliners, business jets, military aircraft and unmanned aerial vehicles in mind. The innovative antenna will open up the aircraft markets to high data rates and low latency satellite communications. The High Throughput Satellite (HTS) communications, of up to 2 Gbps, provide the wideband video streaming and full motion video capabilities that aviators have been waiting for. The capability is ideally suited to continuously track fast moving low earth orbit (LEO) satellites where the analogue phase variation allows continuous electronic beam steering. Multiple simultaneous satellite tracking is possible.

This new product sits within Arralis’ family of versatile communications for space, aerospace, transportable and on-the-move applications. This antenna will be of great benefit to designers of aircraft as now a simple, reliable and flat beam steering and continuous tracking antenna can be realised. According to Gary Soul, the Arralis VP of Business Development, “At the Farnborough Airshow we’ll be exhibiting the Ka band antenna and highlighting how the Arralis new monolithic microwave integrated circuit (MMIC) phase-shifters have enabled this innovative development. We have in essence developed the technology that allows users to continuously track and communicate with Low-Earth-Orbit (LEO) satellites in a form that can be easily integrated onto aircraft. Fleet operators, network providers and platform users should be very pleased with this innovative technology and the attendant economies of scale that volume production should allow.”
