“…Several studies are conducted to achieve a bandpass behavior that fulfills modern technological market needs such as compact size, sharp roll-off rate, wide stopband, and low passband insertion loss [5][6][7][8][9]. Various techniques are carried out to achieve the required bandpass behavior as in [10][11][12][13][14][15][16][17]. In [10], the defected ground structure is used to obtain a wide band stop behavior while passing all frequencies in the range of 2.4-14.3 GHz.…”

“…Various techniques are carried out to achieve the required bandpass behavior as in [10][11][12][13][14][15][16][17]. In [10], the defected ground structure is used to obtain a wide band stop behavior while passing all frequencies in the range of 2.4-14.3 GHz. The stepped impedance resonator (SIR) is one of the most commonly used techniques to provide a bandpass behavior and it succeeded to achieve a triple band (1.85 GHz, 2.575 GHz, and 3.05 GHz) with skew-symmetric (0-degree) tapped-feed structure as in [11].…”

In this paper, a band-pass filter (BPF) based on split-ring resonator (SRR) using a 3-D printing technique for C-band applications is introduced. The proposed filter is designed to operate at a frequency of 3.9 GHz. An innovative technique for printing the substrate with a size of 24 x 24 x 1.1 mm3 using PLA dielectric material is implemented. The copper sheet with a thickness of 0.1 mm is printed on the upper and lower faces of the substrate. First, the SRR band stop filter (BSF) is introduced then two L-Stubs are inserted to implement an additional band stop region, and this rejoin is adjusted to obtain a band-pass region between the two stopbands. The BPF is operated at a 3-dB bandwidth extended from 3.5 GHz to 4.3 GHz with an S21 level of -0.2 dB for the simulated results while it achieves a 3-dB bandwidth within 3.6 GHz to 4.2 GHz (15.3 %) with an S21 level of -1.8 dB for the measured results.
