Abstract

The paper depicts the filter design for millimeter wave range using defected ground structure (DGS) technique. DGS is mainly used for reduction in size of filter design resulting in compactness of model with enhanced efficiency to cope with the latest technological demands. Designs with DGS provides improvements in the optical and millimeter devices. The simulations are carried using HFSS V13. The design is carried out on RT/ Duroid 6002 with loss tangent (tan δ) 0.0012 with outcomes as return loss of more than 27dB and insertion loss near to 1dB. It also provides better selectivity to avoid spurious signals and higher fractional bandwidth. The proposed design is used for the application of automobiles, sensors, communication etc.
