There is the Sampson radar used on the Type 45 warships. And the first fighter AESA of all, which is on the Japanese F-2. The MiG-35 has a prototype AESA radar. AESA also appears in satellites as well.
Lets get this troll banned.
the first operational AESA was Japanese navy,enter service in 1989it adapted rotating antenna,rather than fix antenna,but it uses hybrid circuit rather than more modern monolith circuit.
