Abstract :
In this paper are presented some investigations on micro- strip defected ground structures (DGS). It is shown that the presence of a slot in the ground plane can substantially enhance the electric coupling, or the electric part of a mixed coupling between resonators and its external feedings. The proposed technique can eliminate the very narrow coupling gaps needed for a tight coupling and thus can relax the fab rication tolerances.
