摘要： An electric transmission structure for implementing a transfer function with finite real-frequency transmission zeros, which comprises a main body comprised of a plurality of resonant cavities placed adjacent to each other with inductive coupling irises between adjacent cavities, the resonant cavities being arranged symmetrically relative to a plane of conjugate symmetry, said main body synthesizing the linear phase part of the filter transfer function, and at least one pair of pole resonant cavities arranged symmetrically relative to said plane of conjugate symmetry, each of said resonant cavity pairs synthesizing a pair of finite real-frequency transmission zeros of the filter transfer function, with the respective pole cavities of each pair being connected across the input and output ends of the main body through phase-shift waveguides having defined phase-shift lengths.
