Two coplanar waveguide (CPW) low pass filter configurations based on rectangular dumbbell shaped Symmetric-DGS (SDGS) and Asymmetric-DGS (ADGS) have been designed and fabricated. For the designed filters, the equivalent RLC parameters have been extracted. Performance assessment of these filters has been carried out based on various parameters like, cut-off frequency, pass-band width, pass-band insertion loss, attenuation at resonant frequency, etc. The fabricated CPW-ADGS filter shows pass-band width of 0.9 GHz with attenuation at resonant frequency of -23 dB. IE3D simulation results and theoretical results show good agreement with measured results
