INTEGRATED MULTI-BAND ANTENNA

摘要

PURPOSE: An integrated multi-band antenna is provided to markedly reduce the number of repeaters and base stations by supplying a plurality of mobile telecommunications services from a single base station and a single repeater. CONSTITUTION: A first antenna device(100) operates in a first frequency band. A second antenna device(200) operates in a second frequency band. A third antenna device(300) operates in a third frequency band. The first to third antenna devices are integrated within the physical space of a single conventional antenna device. The second antenna device is positioned on the upper side of the first antenna device. The third antenna device is positioned on the central part inside the first antenna device and is regularly separated from the second antenna device. Each of the first to third antenna devices has the narrow-band property of operating in one frequency band. Each of the first to third antenna devices has the wideband property of operating in two or more frequency bands.
