<p>A repeater antenna (130, 400, 500, 600, 700) comprising a plurality of radiation elements (410, 412, 414, 416, 418) arranged in a first electrically conducting layer or plane, the repeater antenna being characterized in that the radiation elements are given such individual phase shift properties with regard to an incident plane electromagnetic wave that a plane electromagnetic wave (120) which is incident on the repeater antenna will be reflected from the repeater antenna with a beam angle (ß) and a beam shape (a) which differ in a predetermined way from the beam shape and beam angle which would have been caused by said incident wave by reflection in a reflecting plane with the mechanical shape of the repeater antenna.</p> |
