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 and 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 also arranged to prevent electromagnetic propagation in a frequency band of operation from propagating from the at least one first waveguide in directions other than through the at least one distribution layer feed and the one or more radiation elements. The distribution layer includes a plurality of distribution modules and a positioning structure, the positioning structure is arranged to fix the distribution modules in position.
