<p>The present invention discloses a repeater antenna (130, 200) comprising a plurality of radiation elements (210-260) arranged in a first electrically conducting layer or plane. The repeater antenna also comprises a ground plane (320) spaced apart from the radiation elements by a layer of dielectric material (310), and the radiation elements are each given such an extension (L<sub>1</sub>, L<sub>2</sub>, L<sub>3</sub>) and such a distance (D<sub>12</sub>, D<sub>23</sub>) to neighbouring radiation elements that an incident electromagnetic wave (110) will reflect from the repeater antenna at an angle (????<sub>2</sub>) that by a predetermined amount will be greater or smaller than the incident angle (????<sub>2</sub>) of the electromagnetic wave. The repeater antenna is plane, and can be either curved or flat.</p> |
