DOUBLE-SYSTEM GSM AND DCS CELLULAR TELEPHONY ANTENNAS CONSISTING OF MANY TRIANGLES

摘要

The dual multitriangular antennas of the present invention (AMD hereafter) are mainly used in the base stations of both cellular telephony systems (GSM and DCS), providing radioelectric coverage to any user of one cell which operates in any of the two bands or simultaneously in both bands. The object of the present invention is to provide an antenna which radiating element comprises basically several triangles exclusively linked by the vertexes thereof. Its function is to work simultaneously in bands of the radioelectric spectrum corresponding to 890 MHz-960 MHz GSM and 1710 MHz-1880 MHz DCS cellular telephony systems.
