Abstract: Examples of cavity resonators, filters, and communications devices are described. One example of cavity resonator includes a cover, a resonant column, and a cavity. The cover is mounted at an opening of a top portion of the cavity. The resonant column is disposed at a bottom portion of the cavity. A value of distributed capacitance is changed with a distance between the cover and the resonant column, a value of distributed inductance is changed with a distance between the cavity and the resonant column, and a material of at least one of the cover, the resonant column, and the cavity is a plastic metal material. Therefore, when the at least one of the cover, the resonant column, or the cavity deforms, the value of the distributed capacitance or the distributed inductance is changed, to adjust a resonant frequency.
