Abstract
A recently developed technique to design and model an isolated Defected Ground Structure (DGS) has been employed to successfully design and characterize a DGS to be used in between two microstrip patches to reduce their mutual coupling. This is the only technique that can handle isolated DGS and as such has been explored for microstrip antennas in this paper for the firt time. An X-band design has been examined. A prototype is used to obtain measured data which are employed to verify the technique experimentally for microstrip array.
