Abstract

Unas antenas multitriangulares duales para telefonía celular GSM y DCS. Las antenas multitriangulares duales objeto de la presente invención (en adelante AMD) tienen su aplicación principal en las estaciones base de ambos sistemas de telefonía celular (GSM y DCS), dando cobertura radioeléctrica a cualquier usuario de una celda que opere en alguna de las dos bandas o en ambas simultáneamente, la invención preconizada tiene por objeto una antena cuyo elemento radiante está constituido básicamente por varios triángulos unidos exclusivamente por sus vértices. Su función es operar simultáneamente en las bandas del espectro radioeléctrico correspondiente a los sistemas de telefonía celular GSM 890 MHz-960 MHz y DCS 1710 MHz-1880 MHz.
