Abstract
LA INVENCION SE REFIERE A UN METODO Y A UNA DISPOSICION PARA MEJORAR LA COMUNICACION ENTRE UNA ESTACION BASE Y UN NUMERO DE UNIDADES MOVILES QUE PERTENECEN A ELLA EN UN SISTEMA MICROCELULAR. CON UN MAYOR DETALLE, LA INVENCION PRETENDE REDUCIR EL DEBILITAMIENTO DE LA SEÑAL QUE ES UN PROBLEMA CUANDO LAS UNIDADES MOVILES SE ESTAN MOVIENDO LENTAMENTE O SE ENCUENTRAN QUIETAS. DE ACUERDO CON LA INVENCION, EL PROBLEMA SE RESUELVE INTRODUCIENDO UNA DIVERSA SOBRE LOS ENLACES EN EL SISTEMA. EL DISEÑO DE LA ANTENA DE LA ESTACION BASE SE HACE DE MANERA QUE SE PRODUZCA UNA FORMA DE ONDA QUE VARIE EN EL TIEMPO CON PUNTOS DE DESVANECIMIENTO ESPACIALMENTE SEPARADOS. LA COMUNICACION UTILIZA PREFERIBLEMENTE ACCESO MULTIPLE POR DIVISION DE TIEMPO (TDMA), EL CAMBIO EN LA FORMA DE LA ANTENA SE EFECTUA PASO A PASO ENTRE TAJADAS DE TIEMPO ADECUADAS, PREFERIBLEMENTE ENTRE MARCOS TDMA. EL CAMBIO EN LA FORMA DE LA ANTENA SE PRODUCE DE FORMA VENTAJOSA CONTROLANDO UNA ANTENA SECTORIAL (7, 7''). EN UNA CONFORMACION MASADECUADA, LA ANTENA DIRECCIONAL (7'') COMPRENDE UN ELEMENTO ACTIVO (10'') EN FORMA DE UN DIPOLO DE MEDIA ONDA RODEADO POR UN DIELECTRICO (11) QUE, A SU VEZ, ESTA ENCERRADO EN UN CILINDRO QUE ESTA HECHO DE UN NUMERO DE ELEMENTOS PASIVOS (9'') AISLADOS UNOS DE LOS OTROS. EL CAMBIO DE LA FORMA DE LA ANTENA DE LA ANTENA DIRECCIONAL SE PRODUCE CONMUTANDO ELECTRICAMENTE LOS ELEMENTOS PASIVOS.
