| description | A rigorous TE solution to the dielectric wedge antenna
fed by a slab waveguide of the same material is presented.
The method of solution involves modeling the wedge as a sequence
of step discontinuities and uses an iterative procedure to track
forward and backward partial wave fields, expressed as modal expansions,
to obtain the rigorous field solution. Radiation patterns
of directive gain are presented. All patterns smoothly decrease
from a maximum in the endfire direction and exhibit extremely
low side lobe levels. Longer length wedges or smaller dielectric
constant materials are shown to produce higher directivity and
smaller half-power beamwidths. For slender, gradually tapered
wedges, the reflection coefficient of the guided (surface) wave
at the input to the wedge is very small indicating a low VSWR
for tapered dielectric antennas and there appears to be no gain
limitation with antenna length for these antennas. |
