Abstract

"DISPOSITIVO DE RADIOCOMUNICAçãO PORTáTIL, E, SISTEMA DE ANTENA PARA TRANSMISSãO E RECEPçãO DE SINAIS DE RF DE E PARA UM DISPOSITIVO DE RADIOCOMUNICAçãO PORTáTIL" Um dispositivo de radiocomunicação, compreendendo: um alojamento (78); meios de antena para transmitir e receber sinais de RF; transmitir e receber circuitos arranjados no alojamento; pelo menos uma porção condutora; meios de alimentação de antena; e, uma interface de usuário. Os meios de antena incluem uma antena transmissora (60, 61), e uma antena receptora (60, 61, 65, 78). As antenas transmissora e receptora possuem características de radiação ortogonais uma em relação à outra. As antenas de transmissão e recepção podem ser do tipo de dipolo elétrico ou de dipolo magnético. Um sistema de antena, incluindo uma antena transmissora e uma receptora, é também, revelado.
