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.

Antenna system

An antenna implementation comprises an electromagnetic lens and at least one electromagnetically shielding member. The electromagnetic lens is adapted to guide at least one electromagnetic signal by means of at least a variation in permittivity. The at least one electromagnetically shielding member encapsulates the electromagnetic lens partially so as to direct at least one electromagnetic signal propagating through the electromagnetic lens. The at least one electromagnetically shielding member can advantageously be part of an enclosure; said enclosure encapsulates partially the electromagnetic lens. The antenna can further comprise antenna transmission means that contain wave guides. Said waveguides can advantageously be incorporated into the enclosure. The antenna is particularly suited for implementations using Substrate Integrated Waveguide techniques. SIW techniques allow miniaturization of the antenna and offer the advantage of low energy consumption as may be required in portable devices.
