For decades, High Frequency (HF) communications have been an important, in some cases the only, way of providing long distance communication. For most of that time, both voice and data communications in the HF radio bands (2 - 30 MHz) have been restricted to channel bandwidths no wider than 3 kHz.

Dielectric Materials for Wireless Communication. Book • The frequency determining component (resonator) used in such a high frequency device must satisfy certain criteria. The three important characteristics required for a dielectric resonator are (a) a high dielectric constant which facilitates miniaturization (b) a high quality.
