Amazon’s Project Kuiper shows off satellite antennas

Amazon’s Project Kuiper hasn’t yet said when it’ll start launching satellites or providing broadband internet access from above, but it is sharing details about how customers will get their data.

The $10 billion project, which aims to put more than 3,200 satellites into low Earth orbit, will use an innovative type of phased-array antenna that overlays one set of tiny elements on top of another set, Amazon said today in a blog posting. “This has never been accomplished in the Ka-band,” the company said.

Amazon says the innovation should result in a lightweight, low-cost customer terminal with an antenna that’s only 12 inches (30 centimeters) wide. The hardware is being developed primarily at Project Kuiper’s research and development facility in Redmond, Wash.

“If you want to make a difference for unserved and underserved communities, you need to deliver service at a price that makes sense for customers,” said Rajeev Badyal, vice president of technology for Project Kuiper at Amazon. “This simple fact inspired one of our key tenets for Kuiper: to invent a light, compact phased-array antenna that would allow us to produce an affordable customer terminal.”
