“…By bending the resonant arms at both ends to form a deformed W-shape structure, the effective area is lowered from 655 mm 2 to 249 mm 2 . The proposed deformed W-shaped SIRs BPF is a miniaturization design based on the E-shaped SIRs [17]. We will present the design process in this section.…”

“…We previously presented a quad-band BPF with two E-shaped SIRs and two cross-coupling structures between the input and output feed lines [17]. Each one of the E-shaped SIRs corresponds to the first four resonant frequencies, and two passbands can be easily created after combining with the cross-coupling lines that generate three transmission zeros.…”

A novel quad-band bandpass filter (BPF) consisting of two deformed W-shaped microstrip Stepped-Impedance Resonators (SIRs) with different dimensions is proposed. The W-shaped SIRs are miniaturized from E-shaped SIRs, and each one of the SIRs generates two passbands and thus four passbands centered at 3.18 GHz, 4.51 GHz, 5.46 GHz, and 8.43 GHz with fractional bandwidth of 6.7%, 9.1%, 8.4%, and 8.2% were obtained. Compared with the basic SIR structures and E-shaped structures, the effective area of the miniaturized SIR is reduced by more than 60% and 20%, respectively. The operating frequency bands can be determined by switching the diodes that are connected to the cross coupling lines of the two SIRs. The improved design can be used for 5G and other applications.
