Abstract

Una antena para sistemas de comunicaciones telefónicas celulares, destinada particularmente a estaciones base (RFP = Radio Fixed Part = Parte Fija de Radio) de normas DECT (Digital Enhanced Cordless Telecommunication = Telecomunicación Inalámbrica Digital Mejorada), que es capaz de buscar el mejor camino para el usuario, adaptando la característica direccional de una estación base fija a la posición real de un usuario móvil; caracterizada porque está formada como una antena doble multimodo adaptable, apta para adoptar tanto una configuración de lóbulo estrecho, con orientación variable en un plano horizontal, como una configuración omnidireccional en un semiplano horizontal, siendo similares las dos antenas que componen dicha antena doble, integradas en un mismo sustrato dieléctrico, y trabajando simultáneamente con dos funciones diferentes (soporte de tráfico; búsqueda de orientación óptima), intercambiándose dichas funciones en cada ciclo de recepción-transmisión.
