Élaboration d’un système de mesure du diagramme de rayonnement d'une antenne : application en chambre anéchoïque

Abstract

In this thesis, we have to create a measurement system to validate an antenna prototype by quickly and precisely characterizing its different emission planes. There are two parts to this system: the rotary control system and the data acquisition system. The rotary part consists of two positioners and a program. The reference antenna, whose gain is determined as a function of the frequency, is housed in the first positioner. The control board, a stepper motor and the antenna are tested at the second positioner.
