PURPOSE: A variable type notch cable mounted outside having a dielectric resonance band pass filter is provided to improve a diminution characteristics of a filter. CONSTITUTION: A variable type notch cable mounted outside having a dielectric resonance band pass filter includes an input and output connector(13, 23, 33, 43), a coupling loop(15, 25, 35, 45), a dielectric resonance(11, 21, 31, 41, 51), a window(14, 24, 34, 44), a variable notch cable(26, 36, 46), a frequency control plate and a tuning volt, and a housing. The input and output connector is to input and output a signal. The coupling loop is connected to the connector and transmits a wireless signal. The dielectric resonance resonates at a frequency to want. The window is to couple between the dielectric resonances. The variable notch cable is provided on the outside of a filter to adjust a diminution characteristics. The frequency control plate and a tuning volt are to adjust a frequency finely. The housing is to accept the compositions. |
