COMPONENTS FOR HIGH FREQUENCY TECHNOLOGY, LIQUID CRYSTAL MEDIA AND COMPOUNDS

摘要

The 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 medium, which consists of one or more compounds containing 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 contains a component A, which in turn consists of one or more of said compounds containing 6 to 15 five-, six- or seven-membered rings, preferably 1,4-linked phenylene rings. The present invention also relates to compounds of formula (I), wherein the parameters have the meanings given in the text, and also to the corresponding novel liquid crystal media, to the use and production thereof, and also to the production and use of the components. The components according to the invention are suitable in particular as phase shifters in the microwave and millimetre wave range, for microwave and millimetre wave array antennas and most particularly for so-called tunable "reflectarrays".
