Abstract:
A performance calculation technique for leaky-wave antenna based on
planar layered guided structures is provided. Particularly, a partially filled
rectangular waveguide with long slit on narrow wall and protective cover is considered
as the basis. Expressions for inside and outside magnetic field components
calculated by using the Green's functions method for the stratified regions are
presented. A dispersion equation obtained by fields cross linking in slit plane
is written. The numeric results are provided, dispersion characteristics for
different design features of antenna are presented. The possibility of
radiation pattern calculation is shown.
