Abstract

UNA ANTENA PLANA DE RANURA, INCLUYENDO UNA SUPERFICIE (11) CONDUCTORA PERIFERICA, UNA SUPERFICIE (13) CONDUCTORA CENTRAL, SITUADA EN LA SUPERFICIE CONDUCTORA PERIFERICA, CON UN ESPACIO (2) INTERMEDIO, Y UNA PLURALIDAD DE LINEAS COAXIALES (20, 30). LOS NUCLEOS (21, 31) DE LAS LINEAS COAXIALES ESTAN CONECTADOS A LA SUPERFICIE CONDUCTORA CENTRAL EN DIFERENTES PUNTOS DE LA MISMA, Y ENVUELTAS O CAPAS FINAS EXTERIORES (22, 32) DE LAS LINEAS COAXIALES ESTAN CONECTADAS A LA SUPERFICIE CONDUCTORA PERIFERICA. LA ANTENA INCLUYE ADEMAS UN CONMUTADOR (40) SITUADO ENTRE LAS LINEAS COAXIALES Y UN RECEPTOR DE SEÑALES, CON LO QUE EL CONMUTADOR CAMBIA UNA CONEXION ENTRE UNA DE LAS LINEAS COAXIALES Y EL RECEPTOR DE SEÑALES, Y ASI LA ANTENA RECIBE SEÑAL DE LA MEJOR INTENSIDAD Y FASE POSIBLES.A FLAT SLOT ANTENNA, INCLUDING A SURFACE (11) PERIPHERAL CONDUCTOR, A SURFACE (13) CENTRAL CONDUCTOR, LOCATED IN THE PERIPHERAL CONDUCTIVE SURFACE, WITH A SPACE (2) INTERMEDIATE, AND A PLURALITY OF COAXIAL LINES. (20, 30 THE NUCLEUSES (21, 31) OF THE COAXIAL LINES ARE CONNECTED TO THE CENTRAL CONDUCTIVE SURFACE AT DIFFERENT POINTS OF THE SAME, AND THE ENCLOSURES OR THIN EXTERNAL LAYERS (22, 32) OF THE COAXIAL LINES ARE CONNECTED TO THE PERIFORM CONDUCTIVE SURFACE. THE ANTENNA FURTHER INCLUDES A SWITCH (40) LOCATED BETWEEN THE COAXIAL LINES AND A SIGNAL RECEIVER, WHICH THE SWITCH SWITCHES A CONNECTION BETWEEN ONE OF THE COAXIAL LINES AND THE SIGNAL RECEIVER, AND SO THE ANTENNA RECEIVES A SIGNAL SIGNAL AND POSSIBLE PHASE.
