ANTENNA EVALUATION DEVICE, AND MEASURING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an antenna evaluation device capable of evaluating easily and precisely performance of a mobile terminal antenna in a multichannel wave propagation environment. SOLUTION: An amplitude and a phase of a scatterer 102 comprising a plurality of antennas 102a-102g arranged on a circumference with an equal interval are controlled to control a property of the multichannel wave propagation environment constituted in the vicinity of the center part of a circle by an electromagnetic wave emitted from the scatterer 102. The measured antenna 110 such as a diversity antenna is arranged in the vicinity of the center part of the circle to evaluate the performance under the actual using environment.
