Abstract:
    The disclosed direct-coupled triangular-substrate integrated waveguide cavity filter comprises: some isosceles triangular cavities to form regular polygon with any two near cavities as the initial and final cavity respectively; the inlet and outlet ports on cavity, the coupling window between the initial/final initial cavity and near one, and the cavities set between the initial and final cavities. This invention has well property beyond the pass band, and well square coefficient and selectivity on transfer parameters.
