Abstract :
In this paper, a wideband infinite parallel-plate waveguide antenna array radiating along the broadside direction is modelled using the finite-element time-domain (FETD) method. Based on Floquet´s theorem, only a single unit cell is analysed. At, both, the radiating finite element port and the waveguide finite element port of the unit cell exact boundary conditions are employed. The FETD formulation results are compared with those of a finite-element frequency-domain (FEFD)
