Abstract

A hybrid FEM/MoM method and a finite-difference-time-domain (FDTD) simulator have been employed for the modeling of irregular slot radiators in slotted waveguide antennas. Two typical examples of irregular slots are examined, namely, the T-shaped slot radiator in a bifurcated waveguide and the inclined slot in the narrow wall of rectangular waveguide. In both cases the simulated results are shown to be in good agreement with each other and with measured results.
