摘要：

Use of a simple ring-shaped defected ground structure is experimentally demonstrated to suppress considerable mutual coupling between two cylindrical dielectric resonators. About 5 dB suppression has been obtained near the operating frequency around 3.3 GHz. The radiation characteristics with and without defect in the ground plane are also reported.
