GSM (1.8 GHz), WiMAX (2.86 GHz) and UWB (3.32–5.12 GHz). By integrating two narrow
passbands filter with UWB filter; a tri-band response is achieved. The filter response
performance is improved by introducing the asymmetric SIRs with Defected Ground structure
(DGS). An appearance of transmission zeroes of the proposed structure guarantee the
sharpness, the skirts of scattering parameters of triple-band Band pass filter (BPF). The …
