Abstract

Antena dual en frecuencia para funcionamiento en las bandas de 900 MHz y 1800 MHz, que tiene un recubrimiento conductor rectangular con una abertura de acoplamiento y una red conductora de tira asociada. La antena tiene un recubrimiento conductor (2) con al menos una apertura de acoplamiento (3). Hay una red conductora de tira (4) a una pequeña distancia del recubrimiento conductor, cerca de la apertura de acoplamiento, y al menos un parche conductor (5) en el lado opuesto de la apertura conductora. El recubrimiento conductor esencialmente rectangular está conectado a tierra (14) en un borde, y tiene un extremo opuesto libre. La longitud del segundo borde lateral (11) del recubrimiento conductor es de aproximadamente (2n+1)*{la}{sub,2}/4, donde n es un número natural o cero, {la}{sub,2}=c/f{sub,2} en donde c es la velocidad de la luz y f{sub,2} es la más baja de las dos frecuencias operativas.
