An antenna system comprises a wide-band antenna and a lens body. At least a portion of the antenna is placed inside the lens body. The antenna has at least two antenna portions with ends. The antenna portions define a distance between them, which gradually increases towards the ends defining the aperture of the antenna. The lens body has at least two curved sections that merge into a common material section of the lens body. The common material section is located below the aperture of the antenna. Further, a compact antenna test range is described.

An antenna array has a signal distribution region and a signal emission region. The signal distribution region has a distribution body made from a dielectric material which converts an information signal, fed into an infeed side thereof, into a spatially distributed signal distribution on an opposite distribution side. The signal emission region has a plurality of signal emission elements distributed over the distribution side. The signal emission elements protrude from the distribution body. At least one signal emission element has a phase shift region, in which a phase shift material with an electrically influenceable permittivity is arranged in the signal emission element. By applying a phase shift voltage between at least one pair of electrodes, the permittivity of the phase shift material is influenced and thereby the propagation speed of an electromagnetic signal in the phase shift region is changed.

The present invent discloses an electrically-controlled switching multi-polarization horn antenna, which relates to the technical field of communication antennas. The horn antenna includes a horn antenna body, a polarization controller and a polarization switching apparatus. The horn antenna's control module controls a linear polarization control generation module, a circular polarization control generation module and a polarization selection module to cause the horn antenna to operate in a horizontal polarization mode, a vertical polarization mode, a left-hand circular polarization mode or a right-hand circular polarization mode. The antenna can realize a quick switch between different polarization modes, and the switch is electrically controlled rather than performed by manually replacing the antenna. Using the antenna of the present invent can effectively shorten test time, reduce the number of times replacing antennas by a tester, and more accurately measure characteristics of a device under test in various polarization modes.
