Dual Bandpass Filter, Dual T-Shaped Multimode Resonator, Coupling Model, Geometrical and Physical Parameters


In the Bandpass filter two open stepped impedance resonator is introduce with help of dual-band bandpass filter. The proposed filter having an extra added two open T stabbed impudence resonator in outside 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-band bandpass filter is a simulated design of microwave dual-band bandpass filter is operating at its centre frequencies (1.3, 1.95) GHz which make this filter liable candidate of dual- band bandpass filter. The two pass band return loss 31 and 26 dB is first and second band pass filter A s-parameter result proposed filter has been simulated correctly which shows remarkable characteristics of microwave dual-band bandpass filter using SISRs. The dual-band bandpass filter is design for L band application. The insertion loss less than -5dB db. The ROGER RO3006 substrate by dielectric constant 6.15 thickness 1.27 mm in the prepared filter structure which based at SISR the dual band filter.
