“…As the T-shaped resonator (Figure 2(a-b)) is equivalent to the basic SLR topology presented in Figure 1, the mathematical expressions remain the same. However, the corresponding even and odd input impedances of the inverted U-shaped element (Figure 2(c-d)) is given as ( 6) and (7), and that of the middle U-shaped resonator (Figure 2(e-f)) by ( 8) and ( 9), and finally for the E-shaped resonator (Figure 2(g-h)) by (10) and (12). It is important to mention that the resonant frequencies are obtained by combining the resonance condition and the phase constant equation of the quasi-TEM mode behavior of the microstrip line [15].…”

“…Altaf et al [18], a dual-mode ring resonator with two folded half-wavelength stepped impedance resonator (SIR) is used to design two mmWave single bands BPFs for 34 GHz and 40 GHz, respectively. Furthermore, a non-resonating U-shape node is studied and combined with two dual-mode open-loop resonators to design a dual-band BPF for 5G mmWave applications [12]. Similarly, a Conventional microstrip line structure is used to design a millimeter-wave BPF operating at 28 GHz [19].…”

A compact dual wideband bandpass filter for automotive radar (AR) and 5G millimeter-wave (mmWave) applications with adjustable bandwidths is presented in this work. The filter is based on microstrip dual-mode edge-coupled stub-loaded resonators (SLR). The novelty of this configuration is that it allows independent control of the bandwidths which is not obvious for many reported SLR-based filters. To achieve an overall size of 1.23λ_g× 2.02λ_g, these resonators are coupled and bent int o U-shape, T-shape, and E-shape. The U-shaped resonator, based on a quarter-wavelength transmission line, is coupled to the T-shaped element which constitutes the main feed line to obtain the dual-band response. Having a symmetrical structure, the design i s studied using the even-odd mode analysis. The layout is made using the Ansys high-frequency structural simulator (HFSS) and fabricated on Rogers RO3010 with a thickness of 1.28 mm, a dielectric constant of 10.2, and a loss tangent of 0.0022. The measured bandwidths are 660 MHz and 880 MHz at central frequencies of 23.92 GHz and 28.38 GHz respectively. The measured insertion losses are less than 3.9 dB and the return losses are greater than 17 dB in both bands. A good agreement is obtained between simulate d and experimental results.

“…Moreover, BPF with compact size, low loss, and wide passbands becomes highly potential techniques to fulfil the 5G mobile communications requirements [4][5], which includes the massive multiple-input multiple-output (MIMO) system [6]. A BPF consists of several coupled resonators where the dimensions of the distributed lumped elements and number of resonators characterize the BPF [7].…”

A compact parallel coupled line microstrip bandpass filter (BPF) for sub-6 GHz fifth generation (5G) applications is designed operating between edge frequencies of 3.40 and 3.80 GHz. The design is designed and simulated by means of the Advanced Design System (ADS) software using the flame retardant-4 (FR-4) board as the substrate. The BPF design applies the insertion loss method (ILM) to generate a parallel coupled line filter structure that performs passband permission and unwanted noise attenuation below 3.40 GHz and above 3.80 GHz, respectively. Consistent and relevant performances in terms of matching impedance, return loss (S11), insertion loss (S21), voltage standing wave ratio (VSWR), far field radiation pattern, gain, directivity, and radiated efficiency promise the microstrip BPF design has a potential for sub-6 GHz 5G applications.

“…High-integration, low-cost, and high-speed data transmission are demanded for these application scenarios. As a major element of wireless communication systems, multi-band bandpass filters (BPFs) with compact size, low loss, and wide passbands are envisioned as promising solutions to satisfy the requirements posed by 5G mobile communications [2][3][4]. The Federal Communications Commission (FCC) and the Confederation of European Posts and Telecommunications (CEPT) have recently launched investigations into the feasibility of deploying International Mobile Telecommunications (IMT) services in the 5.9-7.1 GHz band (specifically, US 5.9-7.1 GHz and EU 5.9-6.4 GHz), with the possibility of making all or part of this band available for unlicensed operation [5].…”

This study presents a quad-band bandpass filter with high selectivity, compact size, and highly independent bands using a folded C-shape resonator, short stub-SIR resonator, and two folded L-shape resonators. The suggested structure consists of two separate filters. The upper filter is made up of a short stub-SIR resonator loaded on a C-shape resonator resonating at 2.59 GHz and 3.5 GHz, respectively. The lower filter is made up of two folded L-shape resonators resonating at 4.89 GHz and 6.15 GHz, respectively. The frequencies at which the filter resonates are designed and arranged with high independence. The proposed filter achieves insertion loss of −2.7 dB, −0.7 dB, 2.3 dB, and −0.4 dB, and return loss of −13.32 dB, −11.03 dB, −9.17 dB, and −17.89 dB, respectively. In addition, eight transmission zeros appeared. The proposed design has a compact size of 0.19λg × 0.15λg and is built on an RO4350B substrate with a dielectric constant of 3.66, loss tangent of 0.0037, and thickness of 0.508 mm. Finally, the suggested filter is intended to be used in 5G mobile communications and international mobile telecommunications services.
