Abstract

UNA PLURALIDAD DE AISLANTES (18) ESTAN DISPUESTOS EN ORIFICIOS, DE FORMA RESPECTIVA, DEFINIDOS EN UNA PLACA METALICA (10) DE UNA GUIA DE ONDAS DE UNA ANTENA PLANA DE ONDA POLARIZADA CIRCULARMENTE. CADA AISLANTE (18) DISPONE DE UN AGUJERO (18B; 31) PASANTE Y DE UN SALIENTE (18D). LOS AGUJEROS PASANTES SE EXTIENDEN DESDE LA SALIDA DE LA PLACA METALICA AL INTERIOR DE LA GUIA DE ONDA. EL SALIENTE (18D) SE EXTIENDE HACIA AFUERA DETRAS DE LA PLACA (10) METALICA. EL SALIENTE (18D) DISPONE DE UNA RANURA (18C) QUE ESTA ABIERTA HACIA EL EXTERIOR. CADA UNO DE LOS ELEMENTOS (22) DE ONDULACION DE LA ANTENA DISPONEN DE UNA PARTE (22A) DEL EJE, UNA PARTE (22D) DE BRAZO, Y UNA PARTE (22C) DE BUCLE U ONDULACION. LA PORCION (22A) DE EJE ESTA AJUSTADO EN EL AGUJERO (18B, 31) PASANTE DEL AISLANTE Y SOBRESALE PARCIALMENTE HACIA EL EXTERIOR CON RESPECTO A LA PLACA (10) METALICA. LA PARTE (22B) DE BRAZO SE EXTIENDE DESDE EL EXTREMO SALIENTE DE LA PARTE DE EJE. LA PARTE (22C) DE BUCLE U ONDULACION ES DE UN PERFILSUSTANCIALMENTE HELICOIDAL Y ESTA CONECTADA EN LO ALTO DE LA PARTE (22B) DE BRAZO. CUANDO LA PARTE DEL BRAZO ESTA INTERACCIONADA CON LA RANURA (18C) DEL AISLANTE, TENIENDO EN CUENTA QUE LA POSICION DE LA RANURA DEL AISLANTE HA SIDO AJUSTADA DE ACUERDO CON UNA ORIENTACION DE LA PARTE (22C) DE ONDULACION DE LA ANTENA DEL ELEMENTO DE ANTE, LA ORIENTACION DE LA PARTE DE ONDULACION ES AJUSTADA AUTOMATICAMENTE CON RESPECTO A UNA DIRECCION PREDETERMINADA.
