Innovative Design Concept: Defected Ground Structure for Improved Planar Array

A new resonating type defected ground structure (DGS) is investigated to suppress H-plane cross-polarized (XP) radiation but maintaining the co-polar radiation undisturbed. A composite configuration has been explored to reduce the overall size of the defected area on the ground plane to make a desig...

Summary:A new resonating type defected ground structure (DGS) is investigated to suppress H-plane cross-polarized (XP) radiation but maintaining the co-polar radiation undisturbed. A composite configuration has been explored to reduce the overall size of the defected area on the ground plane to make a design of array easy. A 2\times 3 element DGS-integrated array has been demonstrated indicating up to 14 dB suppression in H-plane XP level.
