Design and Implementation of Dual-Band Bandpass Filter using Tappered E Shaped Dual Mode Open Loop Resonator

In the Bandpass filter two open stepped impedance resonator is introduce with help of dual band pass filter. The proposed filter having an extra added two open stabbed impudence resonator in inside the substrate and the filter design is designed for input output transmission lines where structure is totally coupled. Through this theoretical analysis and full wave simulation, we proceed SLR is ready to have the beneficial that odd mode resonant frequency and perhaps even mode are fixed. Dual bandpass filter is a simulated design of microwave dual bandpass filter is operating at its centre frequencies (1.75, 2.83) GHz which make this filter liable candidate of dual Bandpass filter. The insertion loss less than -5dB. An s-parameter result proposed filter has been simulated correctly which shows remarkable characteristics of microwave dual bandpass filter using SISRs. A dual bandpass filter is design to the dual part wireless communication .Warless network IEEE802.11b operates at 2.4 GHz. Satellite communications 2.31 to 2.36 GHz. The FR4 substrate by dielectric constant 4.4 thickness 1.6 mm and toss tangent 0.02 in the prepared filter structure which based at SISR the dual band filter.
