AB - This work presents a novel leaky-wave antenna
(LWA), conceived from the insertion of a dipole-based
frequency selective surface (FSS) into a top-open rectangular
waveguide. It is explained how the printed circuit has the ability
to control the radiation rate of the leaky modes that propagate
through this structure at a certain frequency. This attribute
makes possible the tapering of the radiation diagram of the
LWA. In particular, it is possible to reduce the sidelobes level.
This feature will be illustrated by performing a cosine tapered
design. Good agreement is observed when comparing the results
obtained from leaky-mode theory with full-wave simulations.
Finally, the limitations of this tapering procedure will also be
presented.
