PURPOSE: A wireless variable band pass filter for mobile communication system is provided to realize a coupling between resonators at a particular region by using each coupling window of the resonators. CONSTITUTION: A wireless variable band pass filter for mobile communication system includes a plurality of variable capacity elements(10) and a plurality of dielectric resonators(30). The variable capacity elements(10) are used for controlling frequencies by varying the capacitance according to the input current of an input terminal. The dielectric resonators(30) are used for generating the electric resonance according to the electric vibration of the output frequencies of the variable capacity elements(10). The dielectric resonators(30) are combined each other by coupling windows(40) formed on arbitrary sides of the dielectric resonators(30).
