Resumen
Experimental results are presented to show how a
planar circuit, printed on a laterally shielded dielectric waveguide,
can induce and control the radiation from a leaky-mode. By
studying the leaky-mode complex propagation constant, a desired
radiation pattern can be synthesized, controlling the main radiation
characteristics (pointing direction, beamwidth, sidelobes
level) for a given frequency, This technique leads to very flexible
and original leaky-wave antenna designs. The experiments show
to be in very good agreement with the leaky-mode theory.
