The array elements are realized as open-ended substrate-integrated waveguides [SIW]. Focus of this paper is on the polarizer of the single antenna and on the realization of the array. Simulation as well as measurement data is presented and discussed.enActive antenna arrayCircular polarizationDigital beam formingSIWSubstrate-integrated waveguideTechnikIngenieurwissenschaftenConference PaperConference Paper
