FIELD: measurement technology. SUBSTANCE: invention is based on possibility of contactless pickoff of re-radiated electromagnetic field from dipole excited by field of measured antenna by means of single-wire transmission line. Gear measuring amplitude-phase distribution of antenna includes signal generator connected to examined antenna, two dipoles put in measured points of antenna aperture, two single-wire transmission lines which one end is connected to proper matched loads and which other end is linked to amplitude and phase meter. Examined antenna is mounted for movement of its aperture relative to system " dipoles-single-wire transmission lines-amplitude and phase meter ". EFFECT: increased measurement accuracy. 1 dwg
