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. %K Teoría de la Señal y las Comunicaciones %K Circuito de quivalencia transversal %K Matriz cargada con antenas de fuga de ondas %K Nonradiative dielectric (NRD) leaky-wave antennas %K Stub-loaded leaky-wave antennas %K Transverse equivalent circuit %K Antena de fuga de ondas dieléctricas de no radiación %~ GOEDOC, SUB GOETTINGEN
