Abstract
This paper presents a dual-polarization broadband array element for the Aperture Array low-frequency (AA-low) 70-450 MHz subsystem of the Square Kilometer Array (SKA). It is based on the notched Vivaldi antenna and does not require a ground plane. Suitable electromagnetic performance with a reasonable mechanical complexity have been obtained.
