ABSTRACT:
A strip line filter has a switching function for being operated without connecting a separate switch to a front end and a back end of the filter for preventing transmission electric power from being lost by a receiving unit, to thereby make the size of the transmitting and receiving system smaller. The strip line filter has a switching function in a transmission line filter, comprising: an inputting unit resonator and an outputting unit resonator, with the inputting unit resonator having a first open stub and a second open stub with the first open stub connected to ground through at least one capacitor; and the outputting unit resonator has a third open stub and a fourth open stub with the third open stub connected to ground through at least one capacitor, and being positioned within a distance of about one wavelength of a pass band frequency from the inputting unit resonator.
