The outer open-ring excites a single resonant mode at a low frequency of 2.45 GHz. The outer annular ring is shorted to the ground plane by a shorting pin to miniaturize the antenna size and ...

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 ...
