Abstract
Ring shaped defected ground structure (DGS) is explored to reduce mutual coupling between two circular microstrip patches. Reduction by about 4 dB has been demonstrated employing simulation and measurements executed in X-band. The defect surrounding a patch also indicates 5-20 dB reduction in its cross-polarized fields. Although some backward radiation, caused by leakage through the defect, is experimentally observed, they always remain at least 15 dB below the co-polar peak level. ©2009 IEEE.
