摘要
An antenna evaluation apparatus includes receiving antennas to be evaluated, scatterer antennas provided around them, signal generators, delay circuits, dividers, phase-shift circuits, and attenuation circuits. A computer controls the delay circuits to add delay times to radio frequency signals, and controls the phase-shift circuits and attenuation circuits to change phases and amplitudes of the radio frequency signals to produce a first fading. The antenna evaluation apparatus radiates the radio frequency signals from the scatterer antennas, thus creating multipath waves including delay and fading around the receiving antenna.
