DEVICE FOR PRODUCTION OF LINEAR VERTICAL POLARISATION OF SIGNAL Russian patent published in 2009 - IPC H01Q11/12 

FIELD: radio engineering.

SUBSTANCE: invention may be used at basic stations of mobile communication, for instance, of GSM 900 standard, to provide for radiation of signal with vertical linear polarisation using antennas with double linear oblique polarisation +45° and -45°. Device makes it possible to obtain linear vertical polarisation of signal using antennas with oblique polarisation. It makes it possible to transfer signal in the range of 900 MHz only with vertical polarisation, even with application of traditional antennas, also multirange ones, namely device intended for obtainment of vertical linear polarisation of radiated signal at frequencies of basic station transmitters with application of antenna with linear oblique polarisation +45° and -45°. Device for production of linear vertical polarisation of signal comprises basic station, antenna with oblique linear polarisation, feeder, phased jumpers, diplexer with inlets arranged with the possibility of proportional division of signals coming to each of diplexer inlets from transmitters of basic station and supply of the mentioned signals to inlets of antenna with oblique polarisation +45° and -45° in equal phase and amplitude to produce total vertical vector of radiated signal polarisation. Diplexer is connected to antenna by means of phased jumpers for preservation of proper phasing of signals.

EFFECT: device is quite simple, ergonomic, industrially applicable, convenient to use, does not require considerable material expenses, and may be used multiply.
