Abstract
A high-frequency device and/or a high-frequency switch including the same may include: a signal electrode; a first ground electrode arranged in parallel with the signal electrode; a first liquid crystal layer disposed between the signal electrode and the first ground electrode; and a first dielectric layer disposed between the first liquid crystal layer and the first ground electrode, and/or between the signal electrode and the first liquid crystal layer. The first dielectric layer may have a dielectric constant that is larger than the dielectric constant of the first liquid crystal layer. The high-frequency device and/or the high-frequency device including the same may be variously implemented.
