Abstract

Coplanar waveguide architectures combined with liquid crystals (LC) technology have been demonstrated with superior performance (i.e. less lossy than inverted microstrips and more compact than waveguides) for millimetre-wave phase-shifting applications, as evidenced by our two generations of proof-of-concept demos. In this paper, we contribute an in-depth evaluation from multiple perspectives of fabrications that aim to push the device's performance limits beyond 60 GHz.
