Zusammenfassung:The disclosure relates to an Active Electronically Scanned Array, AESA (100) comprising at least one planar Printed Circuit Board, PCB (102), a first set of first notch antenna elements (104) arranged on the PCB (102), and a second set of second antenna elements (106); wherein the first and second antenna elements (104;106) are interleaved, wherein each first antenna element (104) is configured to transmit and/or receive, a signal having a first direction of polarization, and wherein each second antenna element (106) is configured to transmit and/or receive, a signal having a second direction of polarization, which is different from the first direction of polarization, characterized in that each second antenna element (106) is a notch antenna element which is comprised in a surface mounted element (105) on the PCB (102), and wherein the first direction of polarization and the second direction of polarization is separated by at least 45°.
