Abstract

La invención comprende una antena de elementos en fase que comprende un número de radiadores de guía de ondas (19) y un sistema de suministro deenergía y que comprende además un circuito de calibración (20, 21, 22) para proveer un impulso deprueba. Conectando directamente el circuito decalibración a los radiadores de guía de ondas se obtiene una calibración más precisa, lo que se debe a que cualquier error de fase y amplitud que surge enlos radiadores de guía de ondas es procesadoen un algoritmo de calibración. En una forma de realización favorable, el circuito de calibración es disenadocomo un sistema de guías de ondas (20, 21, 22).
