This work explores several tunable millimeter wave microstrip devices using a liquid crystal (LC) substrate. The LC substrate can change permittivity by applying an electric bias field which enables tunable behavior. Novel devices investigated and in some cases measured, include patch antennas, true time delay lines (phase shifters), and several filters between 60 GHz and 100 GHz. The liquid crystal, W-1825, is proprietary and developed specifically for millimeter wave applications and shows significantly higher permittivity changes and significantly lower losses than many liquid crystals discussed in the literature
