AB - This letter presents a novel leaky-wave antenna which
combines an image NRD (nonradiative dielectric) guide and a
printed strip circuit. The proposed structure allows for an easier,
cheaper and more flexible tapering mechanism than all previous
leaky-wave antennas in NRD technology. The working mechanism
is explained, and two different tapering strip-circuit topologies
are proposed. Cosine tapered illuminations are designed using a
two-dimensional leaky-mode analysis technique. Simulations with
high-frequency structure simulator (HFSS) three-dimensional
analysis are presented for validation purposes. Also, the influence
of the feeding transitions for each printed-circuit design is studied.
Results show the feasibility of one of the proposed designs, leading
to a tapered radiation pattern with sidelobes level below 20 dB.
