In this article, the adjustability of the multi-channel optical filter including magnetized materials and uniaxial anisotropic metamaterials in the three-dimensional one-dimensional photonic crystal structure in the GHz frequency range has been theoretically analyzed and designed. It is shown that resonant peaks in the transmission spectrum can be created in the presented structure without adding a defect layer, in the absence and presence of an external magnetic field. Therefore, the presented ternary periodic structure can act as an adjustable multi-channel filter using the transmission spectrum of the photonic crystal. Also, the characteristics of the transmission spectrum of the assumed structure can be manipulated by applying an external magnetic field, so that the frequency of the channels can be red-shifted or blue-shifted depending on the direction of the applied magnetic field. In addition, the effect of the number of periods of the structure, the optical axis angle of anisotropic metamaterials (φ) and the incident light radiation angle (θ) on the filtering characteristics of the channels in both TE and TM polarizations have been numerically investigated
