Abstract :
Bandpass Filter is an indispensable part of the wireless communication system. This paper proposes an efficient DGS based microstrip bandpass filter for WiMAX application. Here, initially a chebyshev type of bandpass filter is designed and then the losses occurred in the pass band gain is reduced by introducing DGS which will result in miniaturization of the BPF filter. Several simulations and comparison on various DGS based designs have been demonstrated to validate the proposed design. The proposed bandpass filter is fabricated on a FR4 substrate and the measured results also validate the proposed design. The simulation of the proposed DGS based Bandpass filter design is demonstrated for the passband frequency between 5 GHz and 7 GHz. The simulation results agree with the theoretical ones.
