Abstract
Provided is an antenna device used for evaluating a transmission characteristic or a reception characteristic of equipment under test (EUT) having an array antenna that includes a plurality of antenna elements arranged in a plane at predetermined intervals. The antenna device includes an antenna for receiving a modulated signal radiated by the EUT via the array antenna or radiating a modulated signal to the array antenna. The antenna is disposed at a position on a z-axis perpendicular to the plane defined by the plurality of antenna elements such that a group delay distortion of the modulated signal is reduced in a near-field region.
