FIELD: mobile radio communications engineering, possible use in cell phone networks.
SUBSTANCE: transmitting device for cell mobile radio communications, operating on multiple adjacent frequency bands, includes multiple transmitters, connected to appropriate band filters for filtering output signals of transmitters, combined in multiple groups of output signals, while at least one group contains multiple similar signals, divided by frequency in such a way, that mutual interferences are suppressed between output signal in adjacent bands of frequencies, and also one antenna, having multiple antenna elements, and is made with possible combination of output signal groups in aforementioned single antenna by sending a group of output signals to appropriate antenna elements.
EFFECT: possible combination of three and more adjacent frequency bands in one antenna without using connecting device for 3 db.
