Abstract: The present disclosure relates to a notch antenna structure including a plurality of notch antenna elements arranged in at least a first row (R). Each notch antenna element includes a base portion having first and second opposing surfaces, a first electrically conductive body and an adjacent second electrically conductive body, the electrically conductive bodies extending vertically from the first surface, forming an integral structure, a tapering gap between the two electrically conductive bodies. The notch antenna structure includes a bottom plane for receiving the second surface of the plurality of notch antenna elements and the first electrically conductive body includes a leg portion having a feed arrangement proximate to the tapering gap, the feed arrangement including a feed point.

Abstract: An antenna array is provided. The antenna array includes a plurality of M row antenna structures, each row antenna structure forming a row in the antenna array, M being a positive integer≥2, and a plurality of N column antenna structures, each column antenna structure forming a column in the antenna array, N being a positive integer≥2. Each row antenna structure includes a plurality of row antenna elements, where each row antenna element includes a main body tapering from a bottom portion to a tip portion. The bottom portion of each row antenna element includes a first leg portion having a first feed arrangement, and wherein each row antenna element is joined to at least one adjacent row antenna element so to form a conjoined row of notch antennas.
