Satellite Internet Gets a Makeover: Greenerwave’s Metamaterial Antenna
Key Takeaway
Greenerwave, a French startup, has developed a new type of satellite internet antenna that uses a metasurface instead of a phased array. This new antenna is cheaper, uses less energy, and could enable new applications such as satellite terminals on cars and drones.
Summary
- Traditional satellite internet services require expensive and power-hungry ground terminals.
- Greenerwave’s terminal uses a metasurface, which is a 2D metamaterial designed to manipulate electromagnetic waves.
- Metasurfaces are simpler and cheaper to manufacture than phased arrays, and they use less energy.
- Greenerwave’s terminal will be available by the end of 2024.
- The company is also developing terminals that could be used in 5G networks.
The complete Story
Satellite internet is rapidly expanding, promising connectivity anywhere in the world. However, the ground terminals needed to connect to these constellations of low-earth-orbit (LEO) satellites are often expensive and power-hungry. This is where Greenerwave, a French startup, comes in with a game-changing innovation: a satellite internet antenna that utilizes metamaterials.
This blog post dives into Greenerwave’s technology and explores how it can revolutionize satellite internet access.
Traditional Phased Array Antennas: The Bulky and Power-Hungry Workhorses
Current satellite internet services rely on phased array antennas. These antennas consist of numerous smaller antennas working together to transmit a focused radio beam. This allows them to track moving satellites and maintain a reliable connection. However, phased arrays have significant drawbacks:
- High Cost: The complex electronics required for each antenna in a phased array make them expensive to manufacture.
- High Power Consumption: The constant operation of these electronics leads to high energy consumption.
- Limited Applications: The size and power requirements make phased arrays impractical for mobile applications like cars and drones.
Introducing Greenerwave’s Metamaterial Solution
Greenerwave’s antenna ditches the traditional phased array approach in favor of a metasurface. A metasurface is a two-dimensional metamaterial designed to manipulate electromagnetic waves. In simpler terms, it’s a cleverly engineered surface that can bend radio waves in specific ways.
Here’s how Greenerwave’s metamaterial antenna works:
- Reconfigurable Intelligent Surface (RIS): The core of Greenerwave’s antenna is a surface covered in tiny, adjustable reflective elements. These elements can be switched between different states, affecting how radio waves bounce off the surface.
- Beamforming with Reflection: By carefully controlling the reflective state of these elements, Greenerwave’s antenna can manipulate the direction and properties of a radio beam as it reflects off the surface. This achieves beamforming, similar to phased arrays, but with a simpler design.
Benefits of Greenerwave’s Metamaterial Antenna
Greenerwave’s innovative approach offers several advantages over traditional phased array antennas:
- Lower Cost: The simpler design with fewer electronic components makes these antennas cheaper to produce.
- Reduced Power Consumption: The passive nature of the metasurface significantly reduces energy consumption compared to phased arrays.
- Compact and Lightweight Design: The lack of bulky electronics makes these antennas smaller and lighter, ideal for mobile applications.
These advantages pave the way for exciting possibilities:
- Satellite Internet on the Go: Imagine having reliable internet access in your car, plane, or even on a drone – all thanks to Greenerwave’s low-power, mobile-friendly antennas.
- Broader Market Adoption: The lower cost of these antennas could make satellite internet more accessible to a wider range of consumers and businesses.
- Applications Beyond Satellite: The technology behind Greenerwave’s antennas has potential applications in 5G networks and other areas of wireless communication.
The Future of Satellite Internet: A Brighter, More Connected World
Greenerwave’s metamaterial antenna technology represents a significant leap forward in satellite internet access. With lower costs, lower power consumption, and a more compact design, these antennas have the potential to bring reliable connectivity to a wider range of users and applications. This advancement paves the way for a future where satellite internet is no longer a luxury for a select few, but a viable option for anyone seeking connectivity anywhere in the world.
Greenerwave’s innovation is still in its early stages, but it holds immense promise for the future of satellite internet. As the technology matures and production scales up, we can expect to see these antennas revolutionize the way we access information and connect with the world around us.
