초록
We suggest new attenuator design and formula using quad spiral shaped defected ground structure (DGS). Series resistors and quarter wavelength transmission line that has a role of inverter have been synthesized for attenuator design and novel attenuator structure using quad spiral shaped DGS is fabricated, the measurements show good agreement with theoretical anticipations. The suggested attenuator could remove peak of insertion loss graph through various attenuation method. The various attenuations are obtained by attached pin-diodes, 10-15dB attenuation leveling is realized for validity of suggested design.
