Abstract

The present disclosure relates to a wireless communication node (1) comprising at least one antenna arrangement (2, 2′, 2″). Each antenna arrangement (2, 2′, 2″) comprises at least one antenna port (3), at least two antenna elements (4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b) arranged for providing an antenna beam pattern (8), and a phase control arrangement (9, 9′, 9″) arranged to receive at least one input signal (10) via said antenna port (3) and to determine a plurality of intermediate signal components (11) from said input signal (10) by determining a first set of respective phase shifts (φ1, φ2, 10 φ3, φ4; θ1, θ2, θ3, θ4, θ5, θ6, θ7, θ8) for said input signal (3). The phase control arrangement (9) is further arranged to determine a final signal component (12) for each antenna element (4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b) from said intermediate signal components (12) by determining a second set of respective phase shifts (β1, β2, β3, β4: Φ1, Φ2, Φ3, Φ4, Φ5, Φ6, Φ7, Φ8) for said intermediate signal components (12), wherein the second set of phase shifts (β1, β2, β3, β4; Φ1, Φ2, Φ3, Φ4, Φ5, Φ6, Φ7, Φ8) is arranged to provide a lowered gain of the antenna arrangement (2, 2′, 2″) in at least one direction (D). The present disclosure also relates to a corresponding method.
