Abstract
DISPOSITIVO DE RADIAçãO COMPREENDENDO PELO MENOS UM FILTRO DE REJEIçãO ADAPTATIVO E ANTENA PROVIDA COM O DITO DISPOSITIVO. A invenção diz respeito a uma antena que compreende pelo menos um dispositivo de radiação (100) que é provido com um filtro de rejeição associado com a banda de freqüência de um sinal interferente. A antena inventiva é caracterizada em que o filtro de rejeição é adaptativo de uma maneira tal que ele seja ativado quando o sinal inteferente for detectado e a sua potência for maior que um limiar, e que o dito filtro adaptativo seja desativado quando o sinal de potência detectado do sinal interferente for menor que o limiar.
