English: First experimental phased array antenna, invented by Karl Ferdinand Braun in 1905 in Strasbourg, Germany. This was a 3 element array antenna which transmitted a beam of radio waves whose direction could be rotated electronically to 3 directions 120° apart.

Who invented phased array?

Phased array transmission was originally shown in 1905 by Nobel laureate Karl Ferdinand Braun who demonstrated enhanced transmission of radio waves in one direction.

What was the first phased array radar?

The first fielded phased-array radar, called ESAR (Electronically Scanned Array Radar), was built by Bendix and completed in 1960 [39]. ESAR had IF analog phase shifters and an IF beamformer.
