Arralis is pleased to announce the launch of our new Ka-band Phased Array Beam Steering Antenna at Space Tech Expo Europe.
Our low profile, active Phased Array Beam Steering Antenna has many vital applications for providing satellite communications on the move for aviation and ground communications in remote areas.
Key benefits of Arralis Ka-band Beam Steering Antenna
Arralis engineers have designed the Beam Steering Antenna to have a very low profile while still offering a high gain with 64 elements. The Antenna is electronically steered by using analogue phase shifters and amplitude manipulation to steer the beam and shape the radiation pattern, features which will suit many market applications.
The Antenna's low profile and wide steering range makes the Arralis Beam Steering Antenna ideal for satellite communication on the move as it can easily be fitted to vehicles without affecting their performance and provides a wide coverage.
Why has Arralis Developed a Ka-band phased array electronic Beam Steering Antenna?
Two-thirds of existing flat panel antennas are still mechanically steered. This has limitations in terms of size, weight and reliability. In addition, performance is compromised by the tracking speed required for low earth orbit, high data rate satellite tracking.
A flat panel Beam Steering Antenna can acquire and track multiple satellites with one antenna array; the benefits are simple operation, low-cost installation and long-term reliability.
Key challenges in designing a Beam Steering Antenna
First, the antenna element spacing for this design is small due to the frequency of operation. This makes the total spacing tight which affects the fitting of all components including the beam-forming IC's, power distribution network, digital routing etc. while keeping a low-profile design.
Furthermore, it is a complex and highly integrated design consisting of a Multilayer PCB and incorporating all components within a reasonably sized board. Sequential rotation of the radiating elements is employed to achieve a wider circular polarization bandwidth. The design also offers different and flexible polarizations according to customers' requirements.
What else do you need for full function Ka-band satellite communications on the move?
The Antenna is complemented by Arralis' range of Ka band transceivers and micro-controller. Its design is such that it operates with all common software-defined radios and modems.
DLR's new optical ground station inaugurated
Oberpfaffenhofen, Germany (SPX) Oct 17, 2022
Satellites are increasingly becoming network nodes of the internet. Terrestrial nodes are integrated via fibre optic networks, and satellites can only keep up with current developments on the ground if they are also optically networked. European Commission programmes such as the 'Secure Connectivity Initiative' depend on this technology, as do many commercial networks such as Starlink or Oneweb, which aim to deploy similar developments on their next generation of satellites. At the core of this te ... read more
