SYNTHESIS OF A LEAKY-WAVE ANTENNA FOR A GIVEN FIELD DISTRIBUTION AT AN APERTURE
Abstract
An algorithm is proposed for optimization of a given field
distribution on the aperture of a leaky-wave antenna. The
parameters controlling the field distribution are the depths
of the grooves and widths of the lamellas of a reflection grating
scattering the surface wave of a planar dielectric waveguide.
The proposed method uses the energy characteristics of an
isolated groove to obtain good initial approximation. An example
of optimization of the cosine on-a-pedestal field distribution
is given.
