Abstract: The present disclosure relates to an antenna arrangement including a first antenna configured to operate within a first frequency band and a second antenna configured to operate within a second frequency band. The first frequency band is higher than the second frequency band. Further, the second antenna is at least partly arranged within an illumination-field of the first antenna. Furthermore, the second antenna includes a dipole structure segmented into a plurality of electrically conductive sections, wherein each electrically conductive section is coupled to an adjacent electrically conductive section by a reactive load section.

Abstract: The disclosed subject matter concerns an antenna which comprises a ground plane and at least a first and a second antenna element. Each antenna element comprises a feed point, a cavity, a main body, a tip and at least a first tapered portion and a second tapered portion. Each antenna element is arranged on the ground plane, where said first and second tapered portions extend along the antenna element from said tip towards the ground plane of the antenna element, and where each antenna element extends essentially perpendicularly to said ground plane along a centre axis of the antenna element. Each antenna element has at least a first leg and a second leg, where said first leg extends from said main body to the first feed point, where said feed point is located between the first leg and the ground plane, and where said second leg extends from said main body to the ground plane, and where said second leg is electrically connected to the ground plane.

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.
