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.Dual frequency antenna for operation in the 900 MHz and 1800 MHz bands, which has a rectangular conductive coating with a coupling opening and an associated conductive strip network. The antenna has a conductive coating (2) with at least one coupling opening (3). There is a conductive strip network (4) at a small distance from the conductive coating, near the coupling opening, and at least one conductive patch (5) on the opposite side of the conductive opening. The essentially rectangular conductive coating is grounded (14) at one edge, and has a free opposite end. The length of the second lateral edge (11) of the conductive coating is approximately (2n + 1) * {la} {sub, 2} / 4, where n is a natural or zero number, {la} {sub, 2} = c / f {sub, 2} where c is the speed of light and f {sub, 2} is the lowest of the two operating frequencies.
