Sistema de Medição Automatizado das Características de Irradiação de Antenas

The irradiation diagram is one of the most important characteristics of an antenna, whether miniaturized, compact or large (parabolic). In addition to gain and polarization, the measurement of the irradiation diagram is performed for each plane individually and often manually. Therefore, a measurement system is necessary to perform tests on any antenna, of considerable size. Although available, this measurement process is specialized, expensive, time-consuming and not fully automated. This paper presents an automation system for the measurement process of the antennas irradiation diagram, from the integration of different components through an interface developed in Matlab. The particularity of the developed system is to allow measurement of the polarization in different angles of rotation in an automated way
