“…Waveguide filters have been widely used in various microwave communication systems, due to their high Qfactors and high power capability. Substrate integrated waveguide (SIW), implemented by planar dielectric substrate with linear arrays of metallic via-holes embedded, has attracted much interest due to advantages of high Q-factor, low loss, high power capacity, and easy to be integrated with other planar circuits [1].…”

Abstract-A novel multi-layer third-order substrate integrated waveguide (SIW) bandpass filter with improved lower stopband performance is proposed. TE 201 -mode in folded-SIW cavity is utilized to implement negative cross coupling, and the TE 101 -mode is taken as a non-resonating node (NRN) for implementing bypass coupling. A circular aperture etched on the middle metal layer is used to realize coupling between source and the second SIW cavity. Then, three transmission zeros located below the passband can be obtained to improve stopband attenuation. Meanwhile, better spurious suppression performance above passband is achieved. A filter sample is designed and fabricated with multi-layer low-temperature co-fired ceramic (LTCC) technology. The measured S-parameters agree well with the simulated ones, with its predicted good performance.

“…The split ring and strip wire form MTM for substrate and superstrate with same thickness [14,15]. The MTM superstrate located at quarter wavelength forms partial reflective left handed material which not only acts as a protective shield but also controls the key parameters [4,5,16,17]. The microstrip inset feed is used for exciting the antenna model and adjusted at 50 ohm impedance matching.…”

Abstract-Conformability helps microstrip antenna to mount on any geometry platform and can also be used for multiple frequency systems without any complexity. The designing of a frequency reconfigurable antenna conformal to cylindrical surface using the combination of metamaterial (MTM) and substrate integrated waveguide (SIW) is proposed. The single and dual antenna models resonate at various frequencies of C-band by means of changing the cylindrical curvature. The results also show a considerable improvement in bandwidth and gain for dual antennas as compared to the single antenna. The antenna parameters are simulated on HFSS tool, and validation process is done by experimental setup.

“…Another function of the cylindrical post is to match the output port as the three ports of metallic waveguide T junction power divider cannot be matched simultaneously [19]. The cut-off frequency of the SIW power divider is designed at 8.0 GHz and the initial dimensions can be calculated by empirical formula (1) and formula (2) with good precision under conditions of S/D < 3 and W siw /D > 10 [20,21].…”

Abstract-In this paper, a novel power divider integrated with substrate integrated waveguide (SIW) and defected ground structures (DGS) techniques is proposed to provide both power dividing and filtering functions. The SIW technique holds advantages of low profile, low-lost, mass-production, easy fabrication and fully integration with planar circuits. By integrating with defected ground structures (DGS) technique, the size and cost of system can be effectively reduced as the proposed power divider has a function of filtering which leads to reduction of one filter. In order to verify the design approach, the proposed power divider with equal power divisions at the center frequency of 8.625 GHz is fabricated and measured. The measured results demonstrate that the insertion loss is less than 1.2 dB and the input return loss less than 16 dB across the bandwidth of 1.4 GHz (FBW is 16%). Moreover, the imbalances of the amplitude and phase are less than 0.3 dB and 0.5 degree, respectively.
