FIELD: radio engineering.
SUBSTANCE: instrument for electromagnetic field amplitude and phase distribution measuring in aerials containing additional aerial and amplitude and phase meter, a Fresnel-zone plate is placed at a standard distance from auxiliary aerial, which is capable to move with regard to radiating aperture of the observed aerial so that Fresnel-zone plate focus is at a point of measuring.
EFFECT: improvement of producibility and simplification of design.
