A wideband end-fire array including columns or sub-arrays of flared notch radiating elements spaced along an end-fire axis and fed by a true-time-delay corporate feed network. The feed network includes a corporate feed manifold and a plurality of cables connected between a respective manifold port and a balun comprising a corresponding radiating element. The plurality of cables have corresponding electrical line lengths adapted to provide progressive time delays to signals carried between the radiating elements and the feed manifold so as to equalize the time delays due to spacing of the elements along the axis.

[ What is claimed is:] [1.] A wideband end-fire array of radiating elements, comprising:a plurality of radiating elements arranged end-to-end along a common end-fire axis and spaced apart along the axis by a separation distance, each element comprising a flared notch radiating element; anda true-time-delay corporate feed network connected to the radiating elements, wherein time delay differences in contributions by the individual radiating elements to a composite array signal due to the separation of the elements along the axis are equalized by the corporate feed network.
