Abstract

En fremgangsmåte og et arrangement for justering av et antennemønster, spesielt i et SDMA-system hvor en sender og en mottaker innbefatter minst to antenner. Basisbånd-antennesignaler multipliseres med koeffisienter for forming av antennemønsteret, for å frembringe et ønsket antennemønster. Fasen og styr- ken for et basisbånd-antennesignal måles. På grunnlag av målingen kompense- res forskjellene i fase og styrke mellom antennesignalene ved å justere koeffi- sientene som former antennemønsteret.
