Abstract: Provided is an Active Electronically Scanned Array (AESA) including at least one planar Printed Circuit Board (PCB), a first set of first notch antenna elements arranged on the PCB, and a second set of second antenna elements; wherein the first and second antenna elements are interleaved, wherein each first antenna element is configured to transmit and/or receive, a signal having a first direction of polarization, and wherein each second antenna element 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 is a notch antenna element which is included in a surface mounted element on the PCB, and wherein the first direction of polarization and the second direction of polarization is separated by at least 45°.
