Abstract: An antenna system having a cylindrical electromagnetic lens configured to guide at least one electromagnetic signal to an emerging area by means of at least a variation in dielectric permittivity, thereby generating a beam output from the emerging area. The antenna system has a dielectric member configured to receive the beam output from the emerging area and to focus the beam in an elevation plane perpendicular to a planar face of the cylindrical electromagnetic lens. The cylindrical electromagnetic lens is received in a conductive mounting, and the mounting carries the dielectric member.

Abstract: The present invention relates to improving configuration of wireless communication paths between devices in a video projection system comprising multiple wireless video projectors. When an initial radio communication setup is required between a managing node, e.g. a node comprising a master projector, and a node comprising a slave projector, for example following the powering up of the video projection system, the slave node receives setup information by radio communication means according to a sweeping sequence and transmits information by projecting sub-images. Sub-images advantageously comprise information relative to settings of the master node allowing reception in the corresponding slave node of a radio signal transmitted by the master node.
