DESIGN OF COPLANAR WAVEGUIDE TRIPLE-BAND BANDPASS FILTER FOR MINIMIZING THE INSERTION LOSS ON X-BAND APPLICATION IN COMPARISON WITH THE MICROSTRIP TRIPLE-BANDPASS FILTER

Aim: To design a compact Innovative Coplanar Waveguide (CPW) triple-band Bandpass Filter (BPF) for low band (8 - 12 GHz) and compared with Microstrip Triple Bandpass Filter (MTBP). Materials and Methods: The proposed design is based on the CPW triple-band bandpass filter, which consists of a simple rectangular frame constructed on a 1.6 mm thick commercially available Rogers 10i MM material substrate. The sample size of the work is 20 (i.e for each group 10) and G power is 80%. Results : The simulated and experimental results for triple-band pass filter insertion loss is increased to -1.958 dB,-1.407 dB,-1.94dB at 8.75 GHz,10GHz,10.35GHz.The obtained significance value is.044 (p < 0.05). Conclusion: The evolution and development of the CPW triple-band pass filter designed for wideband applications. The simulated results show that the insertion loss of a triple band pass filter has significantly increased for the CPW triple-band pass filter.
