This press release seems pretty light on information. This could be a phased array antenna according to this review (which seems to be focused on airplane-mounted devices):

> "Currently the most popular alternative to Gimbal antennas are Phased Array Antenna flat panel antennas, which are composed of many radiating elements that can be thought of as numerous, tiny, fixed antennas. Each one has a phase shifter which forms beams by shifting the phase of the signal emitted from each of the radiating elements (tiny antennas). This provides a constructive/destructive interference which may be used to steer the beam(s) in a particular direction. This entire process is all electric, so the beam direction can be controlled and pointed instantaneously in any direction. It is able to track the movement of a satellite in the sky, regardless of the movement of the car, boat, airplane, or train."
- HyperSane 4y agoThe current Starlink antenna is phased-array.
- nynx 4y agoYes, all starlink user terminals are phased arrays.
- HyperSane 4y agoThey have to be due to how rapidly the sats move in and out of view.
- iwillbenice 4y agoAlso frequency re-use. They will talk on the same frequency to multiple ground terminals, but pointed different directions from the satellites perspective.
- HyperSane 4y agoDid not know that, neat. Phased arrays are so cool.
- p5a0u9l 4y agoThe flat panel is a phased array dead give away. The performance and cost advantages of digital beamforming are such that you can pretty much assume any high tech antenna is a multi channel array.
