Abstract
An apparatus including an array of dual-polarized antenna elements. Each antenna element includes a pair of orthogonal polarization feeds, and a coupler configured to couple, in the near field, the orthogonal polarizations. The apparatus also including control circuitry configured to control, for each polarization, for each antenna element, a power adjustment and a phase adjustment applied to signals of the respective polarization feeds. The apparatus further includes measurement circuitry configured to measure, for each polarization, for each antenna element via its respective coupler, a power and/or a phase of a signal transmitted from the respective array. The apparatus also includes calibration circuitry configured to adjust, for each polarization, for each antenna element, the power adjustment and/or the phase adjustment applied to signals of the respective polarization feeds in dependence upon the measurement, for each polarization, of power and/or phase of the signal transmitted from the respective antenna element.
