Abstract

UNA ANTENA QUE INCORPORA UNA RANURA Y DISTINTOS ELEMENTOS DIPOLO EN OREJA. LA ANTENA COMPRENDE UN PLANO A TIERRA CON UNA RANURA EN SU INTERIOR, Y DIVERSOS ELEMENTOS EN OREJA INCORPORADOS A UN LADO DEL PLANO DE TIERRA A LO LARGO DE LOS BORDES ELONGADOS DE LA RANURA. LOS ELEMENTOS EN OREJA ESTAN ORIENTADOS ORTOGONALMENTE AL PLANO DE TIERRA Y EN LA MISMA DIRECCION. TIPICAMENTE, LA DIVERSIDAD DE LOS ELEMENTOS EN OREJA ESTAN DISPUESTOS EN UNA RELACION SIMETRICAMENTE OPUESTA A LO LARGO DE LOS BORDES ELEONGADOS DE LA RANURA. LA VARIEDAD DE LOS ELEMENTOS EN OREJA COMPRENDE GENERALMENTE DOS ELEMENTOS EN FORMA DE CUADRANTE QUE TIENEN LOS CENTROS DE LOS RESPECTIVOS ELEMENTOS EN FORMA DE CUADRANTE DISPUESTOS EN, O CERCA DE, LOS BORDES EXTERNOS DE LA RANURA Y DE LOS BORDES EXTERNOS DE LOS ELEMENTOS EXTENDIDOS HASTA CERCA DE LA MITAD DE LA RANURA. LOS ELEMENTOS EN OREJA PUEDEN SER ROTADOS CON RESPECTO A LA RANURA PARA PODER AFINAR LA DIRECCION DE POLARIZACION. EN UNA ANTENA TIPICA, UNA VARIEDAD DE RANURAS SON EMPLEADAS, Y ESTA INVENCION PERMITE EL USO DE RANURAS ORIENTADAS ALEATORIAMENTE, O REGULARMENTE ESPACIADAS, QUE SON ALIMENTADAS POR MEDIO DE GUIAS-ONDA RECTANGULARES CONVENCIONALES O LINEAS RAYADAS ENCAJADAS. UN CAMPO DE RADIACION POLARIZADA CON UNA POLARIZACION ARBITRARIAMENTE CONTROLADA SE PRODUCE SELECTIVAMENTE MEDIANTE EL CONTROL DE LAS POSICIONES RELATIVAS DE LOS ELEMENTOS DE RANURA Y EN OREJA. TIPICAMENTE, SI TODA LA ENERGIA RADIA DE LOS ELEMENTOS EN OREJA, LA ANTENA ES POLARIZADA A LO LARGO DE LA RANURA. SI TODA LA ENERGIA RADIA DE LA RANURA, LA ANTENA ES POLARIZADA A TRAVES DE LA RANURA. CUANDO AMBOS ELEMENTOS, LA RANURA Y LOS EN OREJA RADIAN ENERGIA, LA ANTENA ES POLARIZADA LINEALMENTE, SI AMBOS ELEMENTOS, RANURA Y EN OREJA RADIAN EN FASE, CIRCULARMENTE POLARIZADA SI AMBOS ELEMENTOS, RANURA Y EN OREJA RADIAN CON IGUAL AMPLITUD Y LA DIFERENCIA DE FASE ENTRE ELLOS ES +/ POLARIZADA SI LA AMPLITUD DE EXCITACION Y FASE ASOCIADA CON LOS ELEMENTOS EN RANURA Y EN OREJA NO SON LOS MISMOS.
