  • Enhancing Transformation Characteristics of the Transmission Line for Dual-Band Impedance Matching
    S. Rabbani, S. Narayana, Y. K. Singh
    IETE Journal of Research, 2025
    This article presents a novel scheme for matching real source impedance at uncorrelated dual frequencies to frequency-dependent complex loads (FDCLs). The series transmission line as an FDCL to complex conjugate load (CCL) transformer, which has been used in several earlier reported dual-band matching networks, can be used under limited load conditions. In the proposed scheme, instead of transforming the loads to two complex conjugate points on the Smith chart, the series transmission line is used to transform loads to two uncorrelated points on g = 1 circle, hence matching the real part of the admittance. The leftover susceptances are then cancelled using stubs. This enables dual-band impedance matching under all load conditions at any frequency ratio. Two structures have been presented utilizing the proposed scheme. The complete mathematical description with closed-form solutions for both the proposed structures are provided. Two prototype matching networks for frequency ratios 2.75 and 5.6 using structures I and II respectively are designed and implemented on ROGERS RO4003 substrate having a dielectric constant of 3.38 and a substrate height of 20 mils. The simulated and the measured results are in good accordance.
  • Design of Concurrent Dual Band 3-dB Wilkinson Power Divider Using Dual-Band Real-to-Real Matching Network
    Shadab Rabbani, Shriman Narayana, Umar Farooque, Ajay Kumar, Pawan Kumar Jaiswal, Sandip Kumar
    2025 IEEE Microwaves Antennas and Propagation Conference Mapcon 2025, 2025
    This paper introduces a concurrent dual-band Wilkinson power divider (WPD) using microstrip lines, designed to evenly split power at 700 MHz and 3600 MHz, aligning with 5G bands n28 and n78. Instead of the conventional single quarter-wave transformer, the design employs Monzon's dual stepped-impedance lines to achieve dual-band operation. Simulations, performed in Cadence AWR Microwave Office, confirm the design's effectiveness. The divider was fabricated on a ROGERS RO4003C substrate, and the measured results closely match the simulated data.
  • Concurrent Multifrequency Complex to Real Impedance Matching Network for RF Applications
    S. Rabbani, S. Narayana, Y. K. Singh
    IETE Journal of Research, 2024
    This paper presents a novel technique for matching complex loads to a real source concurrently at uncorrelated frequencies under any load conditions. In the proposed method, a branched stub adds susceptances to the load admittances such that the adjusted loads for all the frequencies can be shifted to g = 1 circle using a single series transmission line; hence matching the real part of the admittances. The left-over susceptance is cancelled through another branched stub. Its adaptability allows it to increase the number of bands by adding transmission lines to the branched stubs. The structure is not subject to any fabrication-related limitations because all the transmission lines used in the design have a characteristic impedance of 50 Ohms. The concept has been validated by designing a prototype matching network for N = 3 and extending it to N = 4, and N = 5 by adding elements to the branched stubs. All the structures are fabricated on ROGERS RO4003 substrate with a dielectric constant, er = 3.38 and height, h = 20 mils. The simulated and the measured results are in good accordance.
  • Design of Third-Order BPFs with Featured Transmission Zeros for Enhanced Selectivity
    Shriman Narayana, V. Sivavenkateswara Rao, Shadab Rabbani, Nagendra Kumar, Sandip Kumar, Yatendra Kumar Singh
    2024 IEEE Microwaves Antennas and Propagation Conference Mapcon 2024, 2024
    This work proposes two third-order bandpass filters (BPFs): one with low-side transmission zero and the other with high-side transmission zero, to improve the selectivity of the passband. To generate the transmission zero, the structure relies primarily on the electrical coupling of two folded open-loop resonators that are internally coupled with a half-wavelength resonator. A half-wavelength resonator exhibits high-side transmission zero of the passband upon symmetric coupling and low-side transmission zero upon antisymmetric coupling. The proposed filters are designed using coupling matrix synthesis, considering the necessary parameters. Two example filters are designed and fabricated at a center frequency of 1.9 GHz, with a bandwidth of 230 MHz and a return loss of more than 20 dB.
  • A Miniaturized Tunable Dual-band BPF With CABW Using Stub-Loaded Multi-Mode Single Resonator
    Nagendra Kumar, Vamsi Krishna Velidi, Sivareddy Devireddy, Avg Subramanyam, V Senthil Kumar, Shriman Narayana
    2024 IEEE Microwaves Antennas and Propagation Conference Mapcon 2024, 2024
    This paper presents a novel multi-mode single resonator-based dual-band tunable bandpass filter (BPF). The layout is designed with a half-wavelength resonator centrally loaded with stubs. To tune the odd and even mode resonance frequencies, two varactors are connected at the open ends of the half-wavelength resonator that participate in the formation of two different passbands. A centrally loaded stub connected at one end to a varactor tunes only the even mode. The ends of the feed lines are also connected to varactors that produce two different resonance frequencies and these frequencies help create two passbands with dual modes. Additionally, transmission zero is generated next to the passband using fixed capacitors between the input and output feed lines. Individual control over the resonance frequencies helps to achieve constant absolute bandwidth (CABW) tunable BPF to both passbands. An example filter has been designed for two different passbands. The first passband is tuned from 1.58 GHz to 1.68 GHz with a CABW of $90 \\pm 3 \\mathrm{MHz}$ and an insertion loss of 3.1 dB. The second passband is tuned from 2.16 GH to 2.31 GHz with a CABW of $190 \\pm 5 \\mathrm{MHz}$ and an insertion loss of 0.9 dB.
  • Concurrent Triple Band Complex to Real Impedance Transformer for RF Applications
    Shadab Rabbani, Shriman Narayana, Yatendra Kumar Singh
    2023 IEEE Microwaves Antennas and Propagation Conference Mapcon 2023, 2023
    This work introduces a novel technique to simultaneously match any three uncorrelated Frequency Dependent Complex Loads (FDCLs) to a real source. Its adaptability allows it to transform any load combination for any frequency ratio. Since all the transmission lines used in the design have a characteristic impedance of 50 Ohms, there isn’t any fabrication related restrictions of the structure. In the proposed scheme, a branched stub adds susceptance to the load admittance such that the modified loads for all the three frequencies can be moved to g=1 circle, hence matching the real part of the admittance using a single series transmission line. The left over susceptances are cancelled through another branched stub. Two triple band prototype matching networks have been presented. All the structures are fabricated on ROGERS RO4003 substrate with dielectric constant, er=3.38 and height, h=20 mils. The simulated and the measured results are in good accordance.
  • A Novel Concurrent Dual Band Matching Network for Complex to Real Impedance Matching for RF Applications
    Shadab Rabbani, Shriman Narayana, Yatendra Kumar Singh
    IEEE Transactions on Circuits and Systems II Express Briefs, 2023
    A novel and simple technique to match Frequency Dependent Complex Loads (FDCLs) to real source impedance at any two arbitrary frequencies is presented. The proposed structure consists of stubs and two 50 Ohms series transmission lines, making it easy to fabricate. This arrangement allows concurrent operability. It has the versatility to transform all types of complex loads at any frequency ratio, which may not be possible with other conventional techniques. In this brief, the limitations of single section transmission line to transform FDCLs to two complex conjugate loads (CCLs) at two frequencies is thoroughly studied. In the proposed scheme, an L-section is used to match the complex load to source impedance at one frequency; and another section consisting of a transmission line and a combination of open-short stub is used to match the load at other frequency. Three prototype matching networks for frequency ratios 6.5, 2.3 and 1.583 are designed and implemented on ROGERS RO4003 substrate having dielectric constant of 3.38 and substrate height of 20 mils. The simulated and the measured results are in a good accordance.
  • Dual Band Complex to Real Impedance Matching Through Dual Band Quarter Wave Transformer
    Shadab Rabbani, Shriman Narayana, Yatendra Kumar Singh
    2023 IEEE Microwaves Antennas and Propagation Conference Mapcon 2023, 2023
    In this paper, a novel technique to match Frequency Dependent Complex Loads (FDCLs) to real source impedance at uncorrelated dual frequencies is presented. The impedance transformation occurs in two steps. In the first step, the load susceptances are cancelled through stubs. The left behind unequal real loads are then transformed to Z0 through dual band quarter wave transformer. In this article, the strength of a combination of open-short stubs and T-section branched stub to cancel any two arbitrary susceptances at two frequencies is thoroughly studied. Also a novel technique to transform two unequal real loads to the port impedance, Z0 is proposed. The scheme allows concurrent operability. The complete mathematical description of all the proposed structures with closed form solutions are provided. Two prototype matching networks for frequency ratios 2.875 and 4.8 are designed and implemented on ROGERS RO4003 substrate having dielectric constant of 3.38 and substrate height of 20 mils. The simulated and the measured results are in a good accordance.
  • Constant Absolute Bandwidth Tunable Symmetric and Asymmetric Bandpass Responses Based on Reconfigurable Transmission Zeros and Bandwidth
    Nagendra Kumar, Shriman Narayana, Yatendra Kumar Singh
    IEEE Transactions on Circuits and Systems II Express Briefs, 2022
    A two-pole reconfigurable and tunable bandpass filter (BPF) with constant absolute bandwidth (CABW) and tunable transmission zeros (TZs) is presented in this brief. The BPF consists of asymmetrical spiral resonators having open ends on one side and capacitor loaded on the other side. The varactor loaded coupled-feed scheme is used at input and output. The two coupling feed-lines are also coupled to each other. It is shown that the control over TZs using the coupling-capacitor loaded between the two resonators leads to two different symmetric frequency responses − first with one TZ on each side of the passband, second with no TZ on either side of the passband. Further, asymmetrical frequency responses having single TZ either on lower or upper side of the passband are achieved by varying the capacitors loaded to the end of coupling-line. CABW while tuning as well as tunable bandwidth (BW) are achieved in all type of responses by using the coupling-capacitor. While tuning, quality factor is maintained by varying the capacitor loaded at the end of the coupled-feed. For the demonstration of the concept, a two-pole tunable BPF is designed and fabricated. The fabricated BPF having size of 13.1 mm $\\times $ 9.4 mm, shows four different responses based on the position of TZs. All four CABW responses of the BPF have a tuning range of 300 MHz. Also, a tunable bandwidth is achieved in every response of the BPF.
