A hybrid shielded-stripline (SS) for broadband TEM singlemode propagation up to 20 GHz is presented. Substrate integrated waveguide (SIW) technology is applied for designs of SS unhindered by the width and materials of the substrate. The hybrid structure, half SIW and half SS, which sandwich the buried-strip, is suggested for a simple fabrication. Therefore, the in-house vertical interconnection technique between two different planes on different substrates is proposed, which results in the realisation of the vias and the hybrid SS structures. The size of the hybrid SS, including transition, is 15.50 × 5.00 × 0.62 mm and the insertion loss is measured to be 1.45 dB/cm at 20 GHz.Introduction: A shielded-stripline (SS) is one of the planar type transmission lines for specific RF applications such as permittivity measurements (highly-sensitive-to-noise-systems) and security communications. It can implement TEM propagation, as well as high power and non-dispersive transmissions. A conventional SS consists of a buried-metal strip in the substrate (dielectric) which is surrounded by top and bottom GNDs, and metallic sidewalls. The surrounding GNDs screen the transmitted signal from external noise [1]. Its application, however, is still limited by complex fabrication and substrate design. Substrate integrated waveguide (SIW) technology can be applied to solve these difficulties and even offers a better integration capability by its planar nature. The SIW is synthesised by top and bottom GNDs surrounding the substrate with via-arrays. It shows similar field distribution to that of the rectangular waveguide [2]. Recently, an advanced study has proposed to propagate TEM waves by combining SIW with the conventional stripline, however, this still suffers from high cost and difficulties in fabrication owing to the via and multilayer structures [3].In this Letter, we propose the hybrid structured SS for a broadband TEM singlemode propagation using silicon micromachining and SIW technologies. The half SIW structure is applied to the design of SS for TEM singlemode propagation irrespective of the width and materials of the substrate up to 20 GHz. The in-house vertical interconnection technique, using sloped sidewalls, is suggested, which results in low-cost and simple fabrication for that multilayered structure and vias.

“…This structure combines the advantage of the coaxial cable and of the planar transmission lines. The metallic vias in SICL can avoid the unwanted parallel plate modes, thereby suppressing the annoying interferences with other lines [5,6]. As another merit, this structure can be mounted on planar circuits and easily integrated with those devices [7,8].…”

This article proposes a substrate integrated coaxial line (SICL) structure with composite right left handed (CRLH) characteristics. The CRLH characteristics were implemented by inserting an inter-digital capacitor (IDC) and strip line into the SICL. To verify the proposed CRLH structure, the effective parameters (ε eff , μ eff ), refractive index (n), propagation constant (β) and Bloch impedance (Z B ) were derived using the retrieved effective parameter method, from which left-handed (LH), right-handed (RH), zerothorder resonance (ZOR) characteristics were confirmed. After completing the CRLH-equivalent circuit from the effective parameters, the component values were validated by comparing the results of a simulation model and a circuit model. The simulation results agreed well with the measured results. This confirmed that the proposed SICL is a balanced CRLH SICL unit cell.

A single-layer broadband transition between air-filled rectangular waveguide (ARW) and substrate integrated waveguide (SIW) operating in W band is proposed. Voltage and current probes are employed to implement the transition. A back-to-back prototype of the proposed transition is designed, fabricated, and measured. Good agreement of the simulated and measured results are obtained. From 80.2 to 98.1 GHz, the measured results show that the insertion loss (IL) is less than 1 dB and the return loss (RL) is better than 10 dB.
