Abstract

LA PRESENTE INVENCION SE REFIERE A UN APARATO TRANSMISOR-RECEPTOR PORTATIL, EN PARTICULAR UN EQUIPO TELEFONICO DE RADIO MOVIL, CON ESCASA IRRADIACION DEL USUARIO, COMPRENDIENDO UN EQUIPO TELEFONICO Y UNA ANTENA, TENIENDO UN PATRON DE RADIACION ASIMETRICO, APLICADO AL CITADO EQUIPO TELEFONICO. DEBIDO A QUE TALES APARATOS, CUANDO ESTAN EN USO, SE COLOCAN EN LOS LATERALES DE LA CABEZA DEL USUARIO, UNA GRAN CANTIDAD DE ONDAS ELECTROMAGNETICAS PASAN A SU TRAVES, EN ESPECIAL CON EL CONTINUO AUMENTO EN LA FRECUENCIA DE TRANSMISION Y LA CONSIGUIENTE DISMINUCION EN LA DIMENSION DE LA ANTENA, LA IRRADIACION DE LA CABEZA DEL USUARIO ES, Y LLEGARA A CONSTITUIR, UN GRAVE PROBLEMA. LA FINALIDAD DE LA INVENCION CONSISTE EN PROPORCIONAR UN APARATO TRANSMISOR-RECEPTOR PORTATIL, CAPAZ DE REDUCIR AL MINIMO LA IRRADIACION DE SU USUARIO. MEDIANTE EL USO DE UNA ANTENA, QUE TIENE UN PATRON DE IRRADIACION ASIMETRICO, TAL COMO PARA SER EXTREMADAMENTE LIMITADO EN LAS DIRECCIONES DE LA CABEZA DEL USUARIO, PUEDE OBTENERSE UNA IRRADIACION CONSIDERABLEMENTE REDUCIDA.THE PRESENT INVENTION REFERS TO A PORTABLE TRANSMITTER-RECEIVER DEVICE, IN PARTICULAR A MOBILE RADIO TELEPHONE EQUIPMENT, WITH LITTLE IRRADIATION OF THE USER, INCLUDING A TELEPHONE EQUIPMENT AND AN ANTENNA TELEPHONE, APPLIED ASYMMETRICAL RADIATION PATTERN. BECAUSE SUCH DEVICES, WHEN IN USE, ARE PLACED ON THE SIDES OF THE USER'S HEAD, A LARGE AMOUNT OF ELECTROMAGNETIC WAVES PASSES THROUGH IT, ESPECIALLY WITH THE CONTINUOUS INCREASE IN THE FREQUENCY OF TRANSMISSION AND THE CONSEQUENTIAL DECREASE IN DIMENSION OF THE ANTENNA, THE IRRADIATION OF THE USER'S HEAD IS, AND WILL COME TO CONSTITUTE, A SERIOUS PROBLEM. THE PURPOSE OF THE INVENTION IS TO PROVIDE A PORTABLE TRANSMITTER-RECEIVER APPLIANCE, ABLE TO REDUCE THE IRRADIATION OF ITS USER TO A MINIMUM. THROUGH THE USE OF AN ANTENNA, WHICH HAS AN ASYMMETRICAL IRRADIATION PATTERN, SUCH AS TO BE EXTREMELY LIMITED IN DIRECTIONS OF THE USER'S HEAD, A CONSIDERABLY REDUCED IRRADIATION MAY BE OBTAINED.
