Does the satellite industry have antenna deficit disorder? - SpaceNews.com Oct 2018
"To connect the masses, megaconstellations will need mega antennas mega cheap. Antenna makers need mega orders to make that happen."

David Hartshorn: “There are business plans, big ones, hanging out there that depend if not entirely then at least to a very large extent on the availability of high-performance, low-cost, high-volume, low-profile antennas,”

"Northern Sky Research expects companies to ship 1.8 million flat panel antennas between now and 2027 with revenues topping $8 billion for the decade."

"For years, antenna manufacturers have produced high-performance alternatives to gimbaled parabolic antennas pointed at geostationary communications satellites. Price tags range from a few thousand dollars to $250,000 depending on the application."

"To work with low Earth orbit constellations, the antennas need to track two or more satellites simultaneously — something parabolic dishes can’t do. They also need to be small and durable, prevent signal interference, instantly find satellites and secure links, degrade gracefully and have great signal efficiency.

“It turns out that according to the laws of physics, you cannot do all those things at the same time,” said Ralph Brooker, president of SatProf"

John Finney, Isotropic: “What OneWeb wants in terms of target price is in the very low hundreds of dollars. We see a way to get there.”
