  • Novel dual-band antenna for multi-mode GNSS applications

    A novel dual-band antenna is proposed for mitigating the multi-path interference in the global navigation satellite system (GNSS) applications. The radiation patches consist of a shorted-annular-ring reduced-surface-wave (SAR-RSW) element and an inverted-shorted-annular-ring reduced-surface-wave (ISAR-RSW) element. One key feature of the design is the proximity-coupled probe feeds to increase impedance bandwidth. The other is the defected ground structure band rejection filters to suppress the interaction effect between the SAR-RSW and the ISAR-RSW elements. In addition, trans-directional couplers are used to obtain tight coupling. Measurement results indicate that the antenna has a larger than 10 dB return loss bandwidth and a less than 3 dB axial-ratio (AR) bandwidth in the range of (1.164–1.255) GHz and (1.552–1.610) GHz. The gain of the passive antenna in the whole operating band is more than 7 dBi.

Each passband is independently designed using two different dual and triple-mode resonators. The proposed dual-band bandpass filter has five transmission zeros. Two transmission zeros are generated by each dual-mode resonator. An additional transmission zero is generated through input/output port coupling. The dual-band bandpass filter application is designed for a 2.4/5 GHz WLAN. Experimental measurements are presented in order to validate the theory.

  • Design of a dual band transparent metamaterial absorber

    In this paper, a transparent metamaterial (MTM) absorber in dual band application is proposed. The absorber is designed using on indium tin oxide (ITO) film for transparency. The unit cell of the proposed absorber consists of an electric LC (ELC) resonator and a ground plate, which are printed on opposite sides of the glass substrate. The ELC resonator comprises two symmetric triangular split ring resonators (TSRRs) for 8 GHz band and another two symmetric TSRRs for 12 GHz band. In low band, the absorber exhibits an absorption of 98.6 % and a full width at half maximum (FWHM) of 6.3 % at 8 GHz. In high band, the absorber exhibits an absorption of 98.2 % and a FWHM of 7.6 % at 12 GHz.

  • A design of E/Ka dual-band patch antenna with shared aperture

    A E/Ka dual-band patch antenna with shared aperture is designed in this paper. The antenna contains two PCB layers; the Ka-band patch is at the top of the upper PCB and perforated with four square windows to set the E-band patches; the E-band patches have H shaped slots to reduce the size of the patches, and the E-band patches are fed through T shaped slots at the ground plane. Experimental model and the simulation results are also given in the paper.

  • A novel dual-band planar inverted-F antenna for WLAN applications

    In order to meet the structural and property demands of the antennas used in WLAN terminals, a novel compact dual-band planar inverted-F antenna is proposed in this paper. The radiating element of the antenna is T-shape slotted and cut off a triangle at its corner. The simulated low and high frequency bands of the presented antenna for VSWR<2 can cover the WLAN 2.4/5GHz bands defined by IEEE802.11a/b/g protocols and HIPERLAN/2 protocol, simultaneously. The radiation patterns of the antenna in free space are approximately omni-directional. The total efficiency and peak gain of the designed antenna also satisfy the needs of the WLAN system. Furthermore, the antenna prototype was fabricated and measured. Good agreement between the measurement and simulation results can be observed.

  • Perturbation method based on resonant type metamaterial transmission lines for dual-band matching networks

    This paper is focused on a perturbation method that allows designing dual-band impedance matching networks for applications where the frequency bands are very close. Such networks are based on resonant type metamaterial transmission lines, namely, artificial lines consisting on a host propagating medium loaded with electrically small resonators. These resonators can be tailored in order to obtain the design requirements of the network, which are not achievable through conventional lines. The main aim of this work is to demonstrate that a perturbation method can be successfully used when the operating frequencies are very close.

  • Compact WLAN dual-band filter using independent band stop resonators combined with diplexer

    In this paper, a highly miniaturized dual-band band pass filter has firstly been developed by embedding all the passive lumped elements into a LTCC substrate for 2.4-2.5 GHz (802.11b) and 5.15-5.85 GHz (802.11a/g) WLAN applications. In order to reduce a size/volume of the filter and improve its performances, the proposed filter was newly designed by using J-inverter transformation technology, independent transmission zero technology and independent band-stop resonators. The J-inverter transformation technology was highly effective to minimize electromagnetic parasitic coupling between the large inductors. The newly applied independent band-stop resonator helped to reduce the number of passive elements in the filter circuit. Finally, designed dual-band filter was combined with simple LC diplexer. The measured maximum insertion losses of the fabricated dual-band WLAN filter were better than 2.3 and 1.3 dB in the lower and upper pass-bands, respectively. Return loss was higher than 15 dB. The overall size/volume of the fabricated filter module was 4.7 × 2.3 × 0.68 mm3.
