| 摘要 |
The present invention relates to a component for high-frequency technology or for the microwave range and millimetre wave range of the electromagnetic spectrum, characterised in that it contains a liquid-crystal compound of the formula I in which the parameters have the respective meanings given in the claims or in the text, or a liquid-crystal medium which itself comprises one or more compounds of this formula I, and to the corresponding, novel liquid-crystal media, to the use and preparation thereof, and to the production and use of the components. The components according to the invention are particularly suitable as phase shifters in the microwave and millimetre wave range, for microwave and millimetre wave array antennae and very particularly for so-called tuneable reflectarrays. |
