摘要:
The invention relates to a liquid crystal medium which contains a component A which consists of one or more compounds of formula (IA), wherein the parameters have the respective meanings indicated in the claims and/or in the text, and to the corresponding, novel mesogenic compounds and to the production thereof. The invention also relates to the use of said liquid crystal media, in particular in components in high frequency technology, and to said type of components which contain the claimed media and to the production and use of said components. The claimed components are suitable in particular for phase shifters in the microwave and in the millimeter wave range, for microwaves and millimeter wave array antennas and most particularly for so-called tunable reflect arrays.
