Abstract :
A Defected Ground Structure in the metallic ground plane of a microstrip line is attractive solution for achieving finite pass band, rejection band and slow-wave characteristics. A split-ring shaped DGS structure has a high selectivity would be preferable owing to the demand for currently expanding communication systems within finite spectrum resources. First of all a split-ring type DGS unit slot is designed underneath a pair of T-shaped microstrip line. [1-4]. Thus just applying a T section at the upper plane of DGS unit a lowpass filter can be changed to a sharp response highpass filters.
