Resumen
In this paper, a new transverse equivalent network
for the modal analysis of stub-loaded leaky-wave antennas is developed.
The derived network is useful for the study of the radiation
of evanescent fields that occurs when they reach the top aperture
of the parallel-plate stub. This transverse network is based, for
the first time, on a nonhybrid formulation of the constituent parallel-
plates modes of order 1 (TE
1 andTM
1 ). The obtained network
is an alternative to the one based on hybrid TE
1 andTM
1
modes, and leads to a simpler transverse resonance equation. The
new equivalent network is validated by obtaining leaky-mode dispersion
curves for a previously studied leaky-wave antenna in nonradiative
dielectric guide technology.
