%X A novel composite right/left-handed leaky-wave antenna
(CRLH LWA), based on periodically loaded parallel-plate
waveguides (PPW) is presented. The loading is obtained by a
rectangular grid of vertical wires and parallel slots etched in the
upper metal plane of the PPW. A novel modal-based iterative
circuit is proposed for the complete analysis and design of this
type of antennas. The coupling between the antenna and freespace
is rigourously modeled using a mode-matching technique,
combined with the Floquet’s theorem. This provides a lossy
dispersive CRLH unit-cell model, whose values are obtained
using a quickly-convergent iterative algorithm. The proposed
method is accurate, extremely fast and it takes into account
the structure physical dimensions. A CRLH PPW LWA has
been designed (without requiring any time consuming full-wave
simulation), analyzed and fabricated using the proposed method.
Very good agreement has been found between measurements and
simulations, validating both, the antenna radiating phenomena
and the proposed technique.
