Abstract: The present disclosure relates to a notch antenna structure (1) comprising a plurality of notch antenna elements (2) arranged in at least a first row (R). Each notch antenna element (2) comprises a base portion (3) having first and second opposing surfaces (4, 5), a first electrically conductive body (6) and an adjacent second electrically conductive body (7), the electrically conductive bodies (6, 7) extending vertically from the first surface (4), forming an integral structure, a tapering gap (8) between the two electrically conductive bodies (6, 7). The notch antenna structure comprises a bottom plane (9) for receiving the second surface (5) of the plurality of notch antenna elements (2) and the first electrically conductive body (6) comprises a leg portion (10) having a feed arrangement proximate to the tapering gap (8), the feed arrangement comprising a feed point (11).

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