  • Microwave distributed-constant band-pass filter comprising projections adjacent on capacitively coupled resonator rods to open ends thereof
    Patent number: 4216448
    Abstract: A microwave distributed-constant filter of a band-pass characteristic having at least one attenuation pole comprises resonator rods, each of which has an open and a shorted end and of which two first are inductively coupled in series through at least one second resonator rod. The first resonator rods are capacitively coupled direct to each other with a projection attached adjacent on at least one of the first resonator rods to the open end thereof. The first resonator rods may be coupled directly to input and output terminals of the filter. Alternatively, two third resonator rods may be interposed between the respective ones of the first resonator rods and the input and the output terminals. The third resonator rods may be inductively coupled direct to each other.
