Abstract :
A tunable resonator based on change of substrate permittivity is fabricated using a new high performance liquid crystal GT3-23001. The results show a measured frequency tuning range of 8.2% compared with a simulated 8.5% around a centre frequency of 2.8%GHz, with a lower insertion loss compared to standard liquid crystals.
