摘要： A band rejection coaxial filter for use with a coaxial transmission line, for example, comprises a casing made of a conductive material and having an internal geometry selected to be in a cut off state with respect to the frequency of a signal being transmitted along the coaxial transmission line. The casing is coupled to the coaxial transmission line and a leakage coaxial cable is provided in the casing, so as to be coupled to the coaxial transmission line through the casing. The leakage coaxial cable is formed of a plurality of leakage openings spaced apart from each other a quarter wave length of the resonance frequency of the resonators in the axial direction for allowing for leakage of the transmission signal. A corresponding plurality of dielectric resonators are provided spaced apart a given distance from and faced to the leakage openings, so that a portion of the transmission signal of the frequency determined by the dielectric resonators is trapped.
