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.
