Abstract :
Functioning of Defected Ground Structure (DGS) employed to suppressing cross-polarized (XP) radiations from a microstrip patch has been investigated. It is observed that the distributions of the substrate fields beneath the patch have strong relation with the XP radiation fields. And this can be manipulated favorably to reduce the XP fields. Both simulated and measured results will be provided. This would help a designer to choose universal configuration of DGS irrespective of patch geometry.
