Abstract

Se proporcionan mecanismos eficaces para generar un conjunto de haces. Un método se realiza mediante un dispositivo transceptor de radio. El método comprende la generación del conjunto de haces como una combinación de al menos dos pares de haces. Cada par de haces está formado por dos haces respectivos con polarizaciones ortogonales. Los dos haces tienen sus direcciones de apuntamiento separadas por una primera separación angular delta1 >0. Los pares de haces adyacentes tienen sus direcciones de apuntamiento separadas por una segunda separación angular delta2 >0. La primera separación angular delta1 es una función de la segunda separación angular delta2.
