Abstract:
1. A method performed in an antenna device for generating one or more signals having desired polarizations, comprising: receiving at least one data stream; inputting each data stream into a respective polarization former; splitting, by each polarization former, the corresponding data stream into one first separate stream and one second separate stream; introducing, by the at least one polarization former, a phase shift between the at least one first separate stream and the at least one second separate stream. transmitting the at least one first separate stream from a first antenna having a first polarization and the at least one second separate stream from a second antenna having a second polarization different from the first polarization, wherein the one first separate stream and the one second separate stream are combined in air resulting in a signal having a formed polarization as a function of the phase shift, wherein each polarization former outputs the one first separate stream via a first output port connected to one or more antennas only of the first polarization, and outputs the one second separate stream via a second output port connected to one or more antennas only of the second polarization.
