FIELD: physics, computer engineering.SUBSTANCE: invention relates to microelectronics and specifically to compact antenna devices used in mobile communication devices and in other equipment operating in the millimetre range. The controlled lens antenna system, having an antenna on an integrated circuit and a dielectric lens antenna configured to generate a plane wave, wherein the dielectric lens antenna is composite and includes a body with relative permittivity eand an insert with relative permittivity e, where e<e, in form of a hyperboloid to facilitate conversion of a spherical wave from a source located at the focal point of the hyperboloid into a plane wave, and a deflecting plate in form of a ceramic plate with contacts, which is configured to deflect the formed plane wave by an arbitrary angle by changing the relative permittivity of parts of the ceramic plate under the effect of a different applied voltage.EFFECT: compact lens antenna system which enables gradual change in directivity without increasing the size of the integrated circuit.5 cl, 5 dwg |
