A Ka-band substrate integrated waveguide bandpass filter has been designed and fabricated using low temperature co-fired ceramic (LTCC) technology. The in-house developed SICCAS-K5F3 material with a permittivity of 6.2 and a loss tangent of 0.002 was used. The size and surface area of the proposed bandpass filter are reduced by exploiting vertical coupling in vertically laminated three-dimensional structures. The coupling between adjacent cavities is realized by a narrow slot. A vertical transition structure between the coplanar-waveguide feed line and the substrate integrated waveguide is adopted to facilitate the internal signal connection. The demonstrated third-order filter has a compact size of 6.79 mm×4.13 mm×1.34 mm (0.63λ0  × 0.38λ0  × 0.12λ0) and exhibits good performance with a low insertion loss of 1.74 dB at 27.73 GHz and a 3 dB fractional bandwidth of 10 %.

This paper proposes a substrate integrated waveguide (SIW) filtering slot antenna. Based on four SIW cavity resonators and a slot locating on the last resonator, a filtering antenna was designed, targeting the near 20 GHz satellite communication band. Simulated in the Ansys-HFSS commercial software, it exhibits a - 10 dB impedance bandwidth of 1.5 GHz and a flat gain of 5.5 dBi in the operating frequency band. Besides, the filtering antenna has good selectivity at passband edges and features such as compact size, low profile, and low cost, making it suitable for Ka-band satellite ground terminals.

Wideband Transition

Aim: In this article, wideband substrate integrated waveguide (SIW) and rectangular waveguide (RWG) transition operating in Ka-band is proposed Objective: In this article, wideband substrate integrated waveguide (SIW) and rectangular waveguide (RWG) transition operating in Ka-band is proposed. Method: Coupling patch etched on the SIW cavity to couple the electromagnetic energy from SIW to RWG. Moreover, metasurface is introduced into the radiating patch to enhance bandwidth. To verify the functionality of the proposed structure back to back transition is designed and fabricated on a single layer substrate using standard printed circuit board (PCB) fabrication technology. Results: Measured results matches with the simulation results, measured insertion loss is less than 1.2 dB and return loss is better than 3 dB for the frequency range of 28.8 to 36.3 GHz. By fabricating transition with 35 SRRs bandwidth of the proposed transition can be improved. Conclusion: The proposed transition has advantages like compact in size, easy to fabricate, low cost and wide bandwidth. Proposed structure is a good candidate for millimeter wave circuits and systems.
