For the differential mode, the OCSRRs are virtually connected ...

  • High-gain Bow-tie Antenna Based on Complementary Split-ring Resonators Enhanced Substrate-integrated Waveguide

    This paper presents a high gain bow-tie antenna fed by the new type of fully planar substrate-integrated waveguide composed of coupled complementary split- ring resonators (CSRR-SIW). The antenna structure is fully planar, and the CSRRs and the bow-tie element are sculptured on the top and bottom surfaces. The CSRRs, the bow-tie element and the feedline of the bow-tie element produce three different resonant frequencies. They can combine together by adjusting parameters. By inclining the feed-lines of the bow-tie element by 15°, the gain increased by 0.6 dB-0.9 dB over the working band of 7.31 GHz-10.36 GHz compared with the original antenna. In addition, by loading the metamaterial unit cells of non-resonant parallel-line, the gain of the antenna enhances about 0.7 dB-1.1 dB. Finally, the gain between 6.8 dBi-7.5 dBi over the whole working band is obtained.

  • Compact Bandpass Filter Based on Split Ring Resonators

    The advances in communication technology stands for the need of compact size, easy to fabricate microwave devices. Herein, we propose a robust, tunable, band-pass filter, operating in the X-band (9.1 GHz). Metamaterial based on split-ring resonators (SRRs) is suggested to implement the proposed filter. The proposed design showed an improvement of 84% and 58% in the insertion loss (0.348 dB) and reflection loss (23.8 dB) respectively with respect to previous publications. In addition, the filter provided an acceptable sharpness to be utilized in radar applications. A tunability in the resonance frequency can be easily reached by changing the SRRs gap where a frequency range between 8.62 GHz and 9.46 GHz can be tuned. A fabricated filter is demonstrated where the mismatching between simulation and experimental results is justified.

  • Miniaturized Substrate Integrated Waveguide Bandpass Filters Based on Novel Complementary Split Ring Resonators

    In this letter, a miniaturized substrate integrated waveguide (SIW) bandpass filter is proposed. A novel complementary split ring resonator is etched on the top surface of the SIW, which provides a pass band below the initial cut- off frequency of the waveguide TE10 mode. The band width of the filter can be tuned by changing the coupling of the novel structure. A pair of transmission zeros outside the pass band can be produced. The results of simulation and measurement are in good agreement.

  • Differential Bandpass Filter With Common-Mode Suppression Based on Open Split Ring Resonators and Open Complementary Split Ring Resonators

    Differential (balanced) microstrip bandpass filters (BPFs) implemented by combining open split ring resonators (OSRRs) and open complementary split ring resonators (OCSRRs) are proposed. The OSRRs are series connected in both strips of the differential line, whereas the OCSRRs are paired face-to-face and connected between both line strips in a symmetric configuration. For the differential mode, the OCSRRs are virtually connected to ground and the structure can be modeled, to a first-order approximation, by a cascade of series resonators (OSRRs) alternating with shunt resonators (OCSRRs), i.e., the canonical circuit model of a BPF. These filters have the ability to suppress the common mode by properly adjusting the metallic area surrounding the OCSRRs. An order-3 balanced Chebyshev BPF is designed and fabricated to illustrate the possibilities of the approach. The filter does not require vias (contrary to previous single-ended microstrip BPFs based on OSRRs and OCSRRs), filter dimensions are small, and the common mode is efficiently suppressed with more than 20 dB rejection within the differential filter pass band.

  • Applications of Open Split Ring Resonators and Open Complementary Split Ring Resonators to the Synthesis of Artificial Transmission Lines and Microwave Passive Components

    This paper is focused on the application of open split ring resonators (OSRRs) and their dual counterparts, open complementary split ring resonators (OCSRRs), to the synthesis of composite right/left-handed transmission lines, that is, artificial lines exhibiting backward wave propagation at low frequencies and forward wave propagation at high frequencies. Due to the small dimensions of these resonators, the resulting lines are very compact. Several artificial lines, with different electrical characteristics and topologies, are reported as illustrative examples. It is shown that these artificial lines can be applied to the synthesis of dual-band components and bandpass filters, and two prototype device examples are designed and fabricated in coplanar waveguide technology: a dual-band impedance inverter applied to a dual-band power divider, and an order-3 wide-band bandpass filter. Finally, it is also demonstrated that OSRRs and OCSRRs can be combined for the synthesis of band pass filters in microstrip technology. Since OSRRs and OCSRRs are described by means of series and shunt resonant tanks, respectively, and they are electrically small, their potential to the design of semi lumped planar microwave devices is very high.

  • FEXT Analysis and its Mitigation Using Double-slit Complementary Split-Ring Resonators

    The operating speed of a digital signal and systems are in several GHz range to initiate faster response. Due to this high frequency and operating speed of the signals more and more signal integrity related issues may arise and these issues has to be solved for the better performance of the system. Now a day's integration and miniaturization of digital devices of printed circuit boards (PCBs) are the key features in high speed technology. The printed circuit boards traces are crowded in the design and creates magnetic coupling interference between them. These traces are considered as transmission lines which carrying signal and power between two more points. When current flows through the traces a magnetic field is always set up and interact with the neighboring conductor due to close proximity. The magnetic coupling is mutual and not possible to avoid it. In the result the signal gets affected which degrades the performance of the system to great extent. So, it is necessary to reduce the effect of mutual coupling to improve the performance of the system for its better signal integrity. The mitigation of mutual coupling effect is analyzed and suppression is achieved using metamaterial based complementary split-ring resonators. A new design of double-slit CSRR is used to reduce the crosstalk which is due to coupling. The FEXT analysis is carried out for the frequency range of 5 GHz to 10 GHz.

  • Design of a Miniaturized Antenna Based on Split Ring Resonators for 5G Wireless Communications

    The design of a high-gain and high-orientation rectangular patch microstrip antenna for 5G communication, which works at 3.5GHz with a relative bandwidth of 2.28% and a gain of 7.43dB, is presented in this paper. By theoretical analysis and electromagnetic simulation design, a new type of miniaturized antenna is designed, in which 10 split ring resonators (SRR) metamaterial structures are symmetrically etched on the radiation patch. Compared with the same microstrip antenna without metamaterial structure, the overall size of the antenna is reduced from 40 * 45 mm to 35 * 40 mm, which is reduced by 22.2%. The loading of metamaterials has an obvious effect on miniaturization of the antenna.

  • Miniaturized Evanescent Mode Substrate Integrated Waveguide Filter with Mixed-Coupled Folded Complementary Split-Ring Resonators

    A miniaturized evanescent mode substrate integrated waveguide (SIW) bandpass filter loaded with mixed-coupled folded complementary split-ring resonators (FCSRRs) is reported in this work. Compared with the conventional CSRR, the proposed FCSRR is with enhanced product of equivalent inductance and capacitance, which is beneficial for size reduction of the conventional CSRR. Hence, as the FCSS pair are loaded into SIW, the newly-formed resonator will exhibit evanescent mode resonance characteristic as well, and even achieve smaller physical size as compared its corresponding conventional CSRR-based counterpart. Meanwhile, it has been well-known that, in the SIW section with a pair of face-to-face FCSRRs, a transmission zero (TZ) at the upper stopband can be generated by the mixed coupling between the SIW and FCSRRs. Furthermore, by adding a slot between the splits of the two FCSRRs, a dual- mode resonator is developed, in which the cross-coupling scheme is constituted to produce an extra TZ at the lower stopband of the resonator to improve its selectivity performance notably. To demonstrate the aforementioned idea, a size-miniaturized bandpass filter based on the proposed SIW section with mixed-coupled FCSRRs is realized. Experimental results show that both miniature physical size and good performance are achieved simultaneously, which illustrates that the proposed work is promising in practical radio frequency (RF) and microwave applications.

  • On the use of Printed Complementary Split Ring Resonators for Dual-Band Applications

    The patch antenna is regarded as one of the key components for compact, low cost wireless platforms. In this paper, a novel dual-band patch antenna with complementary split ring resonators (CSRRs) is presented. This antenna is designed to operate at the 915 MHz and 2.4 GHz bands. Furthermore, antenna miniaturization is achieved by etching the CSRR in the ground plane. This reduces the antenna size by 23% when compared to conventional patch antennas. A prototype antenna is also fabricated and tested, and measured results are in good agreement with simulations. Furthermore, the performance influence of the CSRR is discussed.
