Abstract :
The radiation patterns of perturbed two dimensional parabolic reflector fed by a slotted circular cylindrical waveguide for both the TE and the TM modes are examined. The analysis is carried out using Green´s function second identity in conjunction with the Moment Method. Results show that the perturbed geometry achieves various degrees of improvements in most antenna´s characteristics over the plain parabolic reflector.
