COMPOSITE GLONASS/ GPS+GSM-900/1800 SYSTEM Russian patent published in 2014 - IPC H01Q1/00 

FIELD: radio engineering, communication.

SUBSTANCE: composite GLONASS/GPS+GSM - 900/1800 system, having a GLONASS/GPS system antenna with an amplifier, a passive antenna designed to receive and transmit data in GSM networks and two feeders, characterised by that it further includes a metal base covered by a radiotransparent cap; wherein said passive antenna is vertically mounted on the base, said passive antenna being a dielectric plate, on the top edge of one the surfaces of which are deposited two current-conducting rectangles which are oriented with their long sides parallel to the metal base, on the lower edge of the two current-conducting rectangles, oriented with their short sides parallel to the metal base, between the two rectangles, situated on the lower edge, there is a third current-conducting rectangle with a rounded vertex. An inverted L shaped element is attached to the vertex, wherein the GLONASS/GPS system antenna with the amplifier is mounted on the metal base in a plane perpendicular to the dielectric plate and symmetrical to its end part.

EFFECT: increasing the power of signals in the GSM-900/1800 range and reducing the shielding effect of the structure of a GSM antenna on a GLONASS antenna.
