    • The present invention relates to a device for high-frequency technology, or for the microwave region and millimeter wave region of the electromagnetic spectrum, characterized in that it contains a liquid-crystal medium which consists of one or more compounds, which one or more compounds, which contain 6 to 15 five-, six- or seven-membered rings, preferably 1,4-linked phenylene rings, or in that it contains a liquid-crystal medium which itself comprises a component A, which itself consists of one or more of the said compounds, which one or more compounds, which contain 6 to 15 five-, six- or seven-membered rings, preferably 1,4-linked phenylene rings. The present invention additionally relates to compounds of the formula (I), in which the parameters have the meanings given in the text, and to the corresponding, novel liquid-crystal media, to the use and preparation thereof, and to the production and use of the devices. The devices according to the invention are particularly suitable phase shifters in the microwave and millimeter wave region, for microwave and millimeter wave array antennas and very particularly for so-called tunable “reflectarrays”.
    • 本发明涉及一种用于高频技术的设备或用于电磁波谱的微波区域和毫米波区域,其特征在于,它包含由一种或多种化合物组成的液晶介质,所述一种或多种化合物 其包含6至15个五元,六元或七元环,优选1,4-连接的亚苯基环,或者其含有本身包含组分A的液晶介质,组分A本身由一个或多个 的所述化合物,其中一种或多种化合物,其含有6至15个五,六或七元环,优选1,4-连接的亚苯基环。 本发明还涉及式(I)化合物,其中参数具有本文给出的含义,以及相应的新型液晶介质的使用和制备以及生产和使用 的设备。 根据本发明的装置在微波和毫米波区域中是特别合适的移相器,用于微波和毫米波阵列天线,并且非常特别地用于所谓的可调谐“反射阵列”。
