Polarization and energy characteristics control of X-shaped slots in a waveguide using dielectric inserts

Abstract

The computational study of the possibility to elaborate the consistent X-shaped waveguide-slot radiator on the basis of the developed mathematical model was carried out. The optimal energy and polarization characteristics at the resonant frequency can be obtained by means of using dielectric inserts that act as matching elements at the input and complex loading at the output of the waveguide. It is shown that using dielectric inserts in the waveguide provides the possibility of polarization and energy characteristics of an X-shaped slot being controlled. As a result of optimization of the system parameters the high level of axial ratio and radiation coefficient of the field radiated can be obtained with a good matching at the system input.
