It's a phased array, it uses those many little chips to do "beam steering". Check out this video by The Signal Path (a Bell Labs expert!) doing a teardown and explaning parts of it: https://www.youtube.com/watch?v=h6MfM8EFkGg

Setting up Starlink
For anyone interested in a teardown, Shahriar at The Signal Path is a pro and he did one here:
⬐ geerlingguyHighly recommended. Goes deep into the antenna design and overall components (and why it costs so much to manufacture).

Setting up Starlink
There’s a pretty crazy amount of electronics in the dish. They are likely selling it at well below cost at present.Teardown showing PCB at: https://youtu.be/iOmdQnIlnRo?t=2152

⬐ walrus01the closest thing I have ever previously seen to a starlink phased array is the flat panel phased array radar in the nose radome of an air superiority interceptor type aircraft.⬐ geerlingguyThe CEO just mentioned first version of the dish cost $3000 to manufacture, and it's currently down to $1500. Major goal is to reduce manufacturing cost, since they're selling the thing for $500 and taking a loss right now.
