A method for manufacturing a liquid-crystal antenna device is provided. The method includes step (a) providing a first mother substrate. The first mother substrate includes a first region and a second region. The first region has a plurality of first sides. An extension line of at least one of the first sides divides the second region into a first part and a second part. The method also includes the following steps: (b) forming a first electrode layer on the first region and the second region, and (c) cutting the first mother substrate along the first sides of the first region.

An array antenna (A) in a medium (M) comprises a plurality of radiating elements (ER.sub.T) ensuring the transition between the antenna and the medium, the reflectivity of each element depending on a parameter, the reflectivity of a first element being close to that of the medium, the reflectivity of a last element being close to that of the antenna, the reflectivity parameter of the elements varying from one element to the next. A method comprises calculation of a path equal to the sum of the variations of the reflectivity from one element to the next element, optimization of the variation of the reflectivity parameter so that equivalent radar cross-section of the antenna is the lowest possible or the antenna best observes the radiation objectives, determination of the different elements as a function of said parameter, and simulation of the overall reflectivity and/or of the radiation of the antenna.

A reflector includes a substrate, a plurality of reflector structures arranged on or in the substrate and configured to reflect an incident electromagnetic wave. The reflector further includes an electronic circuit that is arranged at, on or in the substrate and configured to control an antenna when the antenna is connected to the electronic circuit.

A system having a concealed communications element like a telecommunication antenna is described. More specifically, The system has a communications element that is concealed by a highly reflective multilayer polymer optical film 200. The first element of the multilayer polymer optical film is a core layer 202 that is made up of a multilayer optical stack. The multilayer optical stack of core layer 202 includes two alternating polymeric layers. The multilayer polymer optical film may optionally also include a protective layer 204 (for example, a hardcoat or an over laminate) that is positioned between the viewer and the core layer. The protective layer 204 may include one or more UV absorbers to aid in durability of the multilayer polymer optical film against UV-degradation. Multilayer polymer optical film 200 may optionally also include an adhesive layer 208 that is positioned between the core layer 202 and a surface onto which the multilayer polymer optical film is to be adhered.
