Abstract

Se proporciona una disposición de antenas. La disposición de antenas comprende un primer conjunto de antenas y un segundo conjunto de antenas. Cada conjunto de antenas comprende elementos de antena de una primera polarización y elementos de antena de una segunda polarización. Los dos conjuntos de antenas están dispuestos para recibir cuatro señales colectivamente, por lo que los elementos de antena de cada polarización en cada conjunto de antenas se alimentan con una respectiva de las cuatro señales. La señal que se alimenta a los elementos de antena de la segunda polarización del segundo conjunto de antenas está desfasada 180° con respecto a por lo menos una de las otras señales que se alimentan a los otros elementos de antena.
