Abstract

SE DESCRIBE UN SISTEMA EMISOR DE DIVERSIDAD ANGULAR PARA RADIOENLACES DE DISPERSION TROPOSFERICA QUE CONSTA DE UN REFLECTOR PARABOLICO Y DOS BOCINAS DE ANTENA (1,2), LA DISTANCIA (D) ENTRE LAS CUALES ES REGULABLE A FIN DE VARIAR EL ANGULO DE DIVERSIDAD DEPENDIENDO DE LAS CARACTERISTICAS DE TRANSMISION DE LA TROPOSFERA DEL RADIOENLACE CORRESPONDIENTE Y DE TENER SIEMPRE EL ANGULO DE DIVERSIDAD OPTIMO BAJO TODAS LAS CONDICIONES DE ENLACE. EL SISTEMA EMISOR TIENE TAMBIEN CUATRO GUIAS DE ONDA (P,S,T,Q) CONECTADOS A LAS DOS BOCINAS (1,2) QUE PERMITEN UTILIZAR POLARIZACION SENCILLA Y DOBLE PARA AMBAS BOCINAS DE ANTENA Y EMPLEAR ESTAS, U OPCIONALMENTE UNA DE ELLAS, PARA RECIBIR Y TRANSMITIR LAS SEÑALES, POR LO QUE EL SISTEMA ES MUY FLEXIBLE.
