Abstract
An antenna arrangement having a stacked layered structure. The antenna arrangement including a radiation layer having a surface. The surface is delimited by a surface boundary. A first and a second slot extend along a first slot axis and second slot axis, respectively, and are arranged on the surface. The antenna arrangement also includes a distribution layer facing the radiation layer. The distribution layer is arranged to distribute a radio frequency signal to the first and second slots. The distribution layer includes a distribution layer feed and a ridge arranged to form a first ridge waveguide intermediate the distribution layer and the radiation layer. The ridge includes a first section connected to a second section via a curved section. The first section extends along a first ridge axis and the second section extends along a second ridge axis different from the first ridge axis.
