Abstract
An antenna arrangement having a stacked layered structure. The antenna arrangement includes a radiation layer including one or more radiation elements, and a distribution layer facing the radiation layer. The distribution layer is arranged to distribute a radio frequency signal to the one or more radiation elements. The distribution layer includes at least one distribution layer feed. Any of the distribution layer and the radiation layer includes a first electromagnetic bandgap, EBG, structure arranged to form at least one first waveguide intermediate the distribution layer and the radiation layer. The first EBG structure is arranged to prevent electromagnetic radiation in a frequency band of operation from propagating from the first waveguide in directions other than through the distribution layer feed and the one or more radiation elements. The radiation layer and the distribution layer are attached to each other with one or more fastening members including respective deformable tails.
