In this paper we have designed and analyzed step impedance resonator based ultra wide-band (UWB) band pass filter using plasmonic MIM waveguide. The UWB band pass filter has been designed by introducing a shot-circuited stub to implement the shunt inductance between two quarter wavelength (λ/4) step impedance resonators. There is a strong coupling between the stubs. The plasmonic UWB band pass filter has been designed at E band (1360-nm to1460-nm) optical wavelength. The band width of plasmonic ultra wide-band band pass filter is very effective compared to narrow-band band pass filter. The reflection and transmission characteristics, variation of reflection and transmission coefficents by varying the dimensions of UWB, field distribution of plasmonic UWB has been realized using full wave simulation by using commercially available CST microwave studio software. The UWB band pass filter can further used for the development of photonic integrated circuits (PICs).

Purpose The purpose of the study is – in Microwave filter design, the performances of passive components are deteriorated by parasitics at gigahertz (GHz) frequency range. A compact and multi-stack electromagnetic band gap (EBG) structure is proposed with improved stop band characteristics at GHz frequency range in this work. This paper proposes a new design for ultra wide band pass filter (resonator BPF) with periodically loaded one-dimensional EBG to achieve the harmonic suppression. This basic EBG structure is developed with combination of a signal strip and ground plane in the slotted section. The resonator BPF is loaded with one EBG, two EBG and three EBGs to improve the stop-band rejection. Design/methodology/approach The proposed filter is with multi-stack EBG cell for achieving good pass band and stop bands performance. Circuit model is analyzed in Section 2. Section 3 discuses band pass filter loaded with one EBG. In Sections 4 and 5, filter with two and three EBG loaded resonators are discussed, respectively. Section 6 is concluded with comparison of simulation and measured results. Findings The stop-band rejection is 20 dB, 40 dB and 50 dB, respectively, in the frequency range of 6 GHz to 20 GHz. The simulation analysis is carried out with advanced system design software. To validate the simulation results, proposed structure is fabricated, and results are found to be in good agreement. Originality/value This paper accounts for designing resonator BPF, which has slow wave pass band and stop band characteristics. Second and third harmonics are suppressed using multi-stack EBG. Various stacks with basic designs are proposed and improved results have been demonstrated which is open for future research.

In this paper, a metamaterial structure based on Frequency Selective Surface (FSS) cell is proposed to achieve an isotropic band-pass filtering response. This filter consists of a planar layer formed by a 3×3 metamaterials cell array with transmittive filtering behavior at 3.5 GHz. This design with 45 mm × 45 mm dimension is then integrated in close proximity at distance of 10 mm with an Ultra Wide Band (UWB) antenna to enhance it’ s performances around a 3.5 GHz operating frequency. Simulation results ensure that filter geometry provides the advantage of polarization independency and also exhibits the angular stability up to 45◦ for both Transverse Electric (TE) and Transverse magnetic (TM) modes. More importantly, enhancement in antenna radiation pattern characteristics is illustrated when the planar FSS layer is integrated at a small distance from the radiator. Moreover, antenna gain was improved to 3.22 dBi, adaptation of antenna port (S11) was increased to -53.26 dB and antenna bandwidth reduction to 1.7 GHz is also detected. All these performances make the proposed design as a good choice used to shield signals in UWB wireless applications especially for connected object in 5G.

In this paper, an Ultra-wide-band (UWB) filter based on composite right/left handed transmission line (CRLH TL) is presented. The structure of the proposed band-pass filter is quite simple, of which the size is 0.5cm×1.5cm. Left-handed capacitor is obtained by couple of microstrip lines, and Left-handed inductance is obtained by the grounded stub. The simulated results indicate that the pass band of UWB filter is 3.4-11GHz, the insertion loss is less than 1 dB and the return loss is smaller than -12.5dB. The performance of UWB filter could meet the requirement of UWB communication systems.
