Abstract: An antenna structure including at least two stacked antenna apertures, a first antenna aperture with first antenna elements and at least a second antenna aperture with second antenna elements. The antenna structure is arranged for operation in at least a high and a low frequency band. The first antenna elements are arranged for operation in the high frequency band and the second antenna elements for operation in the low frequency band. The first antenna elements are arranged to have a polarization substantially perpendicular to the polarization of the second antenna elements. The second antenna elements are arranged in at least one group and each of the group includes a number of second antenna elements coupled in series and arranged to have a common feeding point on a straight feeding structure. One feeding structure is located adjacent to each group of second antenna elements. The direction of the feeding structure is substantially perpendicular to the polarization of the first antenna elements. A corresponding method and a radar system including the antenna structure.

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.
