ABSTRACT:
The invention relates to a multi-face phased array antenna. To prevent crosstalk between the individual faces, each face comprises two cancellers, each of which cancels the crosstalk from an adjacent face. To this end, each canceller receives a reference signal from an adjacent face and is provided with a quadrature mixer and a vector modulator.
