The invention discloses a dielectric filter and communication equipment, which belong to the technical field of communication. The dielectric filter is coated with an external conductor layer. The dielectric filter comprises a first transmission medium, at least one resonant medium and a second transmission medium which are coupled sequentially, wherein an internal conductor layer is clamped between any two coupled media in the first transmission medium, the at least one resonant medium and the second transmission medium; each internal conductor layer is provided with a first coupling window and a second coupling window, wherein the first coupling window is used for coupling electromagnetic waves in a first frequency band, the second coupling window is used for coupling electromagnetic waves in a second frequency band, the electromagnetic waves in the first frequency band and the electromagnetic waves in the second frequency band are orthogonal, and the first frequency band and the second frequency band are not overlapped mutually. The problem of low electromagnetic wave transmission efficiency of the dielectric filter is solved, and the electromagnetic wave transmission efficiencyof the dielectric filter is improved. The dielectric filter and the communication equipment are used for electromagnetic wave transmission.
