DEVICE PROVIDING USE OF COMMON FEEDER FOR TWO ELEMENTS Russian patent published in 2011 - IPC H03H7/38 H01Q1/24 

FIELD: radio engineering.

SUBSTANCE: device includes the first antenna element having the possibility of operating at least on one frequency in the first frequency range, the second antenna element having the possibility of operating at least on one frequency in the second frequency range, radio frequency unit electrically connected to the first antenna element by means of the first channel and electrically connected to the second antenna element by means of the second channel; at that, the first and the second channels are common at their connection point with radio frequency unit; the first frequency-dependent filter located in the first channel and intended to pass frequencies in the first frequency range and to suppress frequencies in the second frequency range; the first full resistance conversion circuit which has the first inductance with the tap located in the first channel, and the second frequency-dependent filter located in the second channel and intended to pass frequencies in the second frequency range and to suppress frequencies in the first frequency range.

EFFECT: providing multi-range operation at decreasing the number of elements.
