Poorly super directed waveguide-slot array antenna axial radiation
Abstract
The directionality properties of the AR based on a dielectric filled metal waveguide of a rectangular cross section with narrow rectangular slots cut in two wide walls are analyzed using the computer simulation. Two variants of such antenna design are studied: with the absorbing element and without it, but with an open radiating end of the waveguide.
As the calculations have shown such axial radiation arrays have an axisymmetric main lobe of the antenna pattern and the directivity factor increased compared to the cophased array and to the dielectric rod antenna with similar dimensions.References
