Abstract :
This paper presents results of a spiral defected ground structure (SDGS) study in grounded coplanar waveguide (GCPW) technology. A SDGS is implemented on the top and bottom ground planes of a GCPW transmission line resulting in stronger attenuation poles. By varying the SDGS degrees of freedom, resonators have been designed for a tuning range from 3.7 to 7.2 GHz. 5 GHz resonators have been fabricated and show good agreement with simulated results.
