Abstract

Antena plana de polarización circular para microondas con dos modos de trabajo que permiten su uso en sistemas monopulso. Está construida sobre una guía radial formada por dos planos conductores paralelos sobre material dieléctrico. La estructura radiante es un conjunto de pares de ranuras dispuestos en anillos concéntricos. Se alimenta a través de cuatro postes centrados en la guía, alimentados a través de una red de distribución impresa. La red conecta las dos entradas de la antena con las cuatro sondas. Cada una de las dos entradas genera un haz diferente. El primero es directivo en la dirección perpendicular al plano de la antena. El segundo tiene un diagrama cónico, con un nulo en dicha dirección, siendo su fase variable en la dirección acimutal. Comparando la amplitud y fase de ambos diagramas se puede obtener la dirección de llegada de la señal, lo que constituye un sistema monopulso.
