The invention refers to a radiation unit comprising a lens (10) having a dielectric refractive lens body (12) that transfers electromagnetic waves. The invention is characterized in that the dielectric refractive lens body (12) has a first relative permittivity εcentre the center and a second relative permittivity εperipheral edge in the edge region of the lens, where the first relative permittivity εcentre and the second relative permittivity εperipheral edge are related by the relation εcentre=1.42 √εperipheral edge+0.58, with a tolerance of 0.2, where |εperipheral edge−εcentre|>0.1 and εperipheral edge>1.5.
