Introduced in "Millimeter-Wave Near-Field Measurements Using Coordinated Robotics. IEEE Transactions on Antennas and Propagation," 6-axis robotic arm – Configurable Robotic Millimeter-Wave Antenna (CROMMA) facility – optimizes antenna properties measurement. Lead researcher Joshua Gordon, citing configurability and repeatability, said this robot permits many ways of doing measurements. At first, robot will measure frequencies from 100–300 GHz with goal of reaching 500 GHz and higher.
