Abstract :
The hybrid metal dielectric structure which is combined a microstrip line section and bounded periodical sequence of slot discontinuities are investigated. The boundary problem for a single discontinuity is solved with the help of spectral-domain approach. For the definition of the parameters of bounded sequences of discontinuities the operator technique is used. If one introduces the slot discontinuity into the T- wave propagation region one can observed the phenomena of leaky modes excitation around the cut-off frequencies of microstrip line is established, They may be classified as surface-wave leaky modes and space-wave leaky modes. The excitation efficiency dependence by the couple value of the discontinuity and basic waveguide is investigated.
