| abstract |
The present invention relates to compounds having at least one CC triple bond of formula (I) with neutral dielectric anisotropy, to their use for high frequency components, to liquid crystal media comprising such compounds and to high frequency components, in particular antennas, in particular comprising such media The present invention relates to antennas for gigahertz and terahertz sectors. The liquid crystal medium provides, for example, phase shift of the microwaves with respect to a 'phase-array' antenna that can be tuned. [Formula I] |
