Abstract :
A CG-FFT method is presented which allows the analysis of antennas with symmetry of revolution with slots in their waveguide walls. Results are successfully compared with measurements and demonstrate the need of including an appropriate model of slots and wall thickness when open ended waveguides are considered.
