Dual multitriangular antennas for GSM and DCS cellular telephony
 The dual multitriangular antennas of the present invention are mainly used and operate in the base stations of cellular telephony systems working in GSM and DCS bands. They provide radioelectric coverage to any user of one cell which operates in any of the two bands or simultaneously in both bands. The invention provides an antenna having a radiating element comprising 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.
