Abstract

The authors propose a moment method analysis for the analysis of a parallel plate slot array, excited by a feed waveguide, based on the Flocket´s theorem. The beam tilt of the incident wave, due to the frequency dependence of the excitation wavelength, is considered by using a complex Hertzian potential and periodic boundary conditions. A phase shift, that depends on the frequency, is included in the periodic conditions. This analysis can also be used for beam scanning arrays.
