Method and arrangement for phase calibration of transmit and/or receive paths of an antenna array

摘要: A method of calibrating transmit and/or receive paths an antenna comprising at least two columns, each which co-located sub-arrays elements, one sub-array element with a first polarization and second polarization, said being connected to respective transceiver device via feeder network. The includes the steps transmitting (S1) measurement signal on receiving (S2) representation other mutual coupling component dependent between element. Further, repeating (S3) step for subset all combinations elements antenna, wherein combination comprises has same or different subsequently comparing (S4) received representations estimating (S5) phase difference based comparison. Finally, (S6) estimated difference.
