Abstract
Un sistema incluye una antena que tiene un sustrato y una pluralidad de elementos de la antena dispuestos en el sustrato. Un dispositivo de procesamiento se configura para medir una función de apertura a través de una apertura de la antena y determinar si al menos uno de los elementos de la antena está bloqueado en base al menos en parte en la función de apertura medida.
