Abstract
An apparatus forms a weight for each signal path associated with an antenna of a plurality of antennas around a test zone in an over-the-air chamber by a comparison of a desired target electric field based on a radio channel model and an electric field obtainable by the plane waves associated with the test zone, the plane waves being transmittable by the antennas and being based on at least one basis waveform in each signal path.
