Abstract :
Defected Ground Structure (DGS) is realized by etching off parts of ground plane in microstrip antenna arrays. By suppressing the surface waves, DGS reduces the mutual coupling between array elements and hence eliminates the scan blindness. Trial and error approach requires many simulations to design DGS. This paper, presents an efficient design procedure for DGS based on Genetic Algorithm and sensitivity analysis requiring a few simulations.
