“…The thickness of substrate influences the cut-off frequency of the propagating substrate modes. Decreasing substrate thickness allows an increase in the cut-off frequency of the substrate modes [4,8]. The transmission loss of the measured PGL is about -5 dB.…”

In this communication, a computational and experimental investigation at terahertz frequencies of Planar Gaubau Line combined with Split Ring Resonator is reported. Different parameters such as gap width, position and gap orientation that tuned the resonance peak are studied. The obtained results are useful for the understanding of coupling mechanism between a radially polarized wave along a metallic strip and a Split Ring Resonator.

“…Following this, two and three-arm coplanar transmission lines were investigated as well as coplanar waveguides [59][60][61][62][63][64][65][66]. More recently, single conductor waveguides (Goubau lines) have been used to route THz radiation and single pulses on chip [67][68][69][70][71]. In most cases, the circuits have been fabricated using conventional metals, but superconductors have also been used [72].…”

This chapter summarizes the trends in terahertz measurements on the surface of rigid and flexible substrates. It focuses on research incorporating fast photoconductive switches to generate and detect on-chip THz pulses using a femtosecond laser. The chapter aims to review progress toward the study of picosecond dynamics and THz spectroscopy of materials and liquids. We emphasize general sub-diffraction techniques for THz spectroscopy, transmission line and waveguide design considerations, time-domain measurements for studies of material dynamics, and provide a survey of recent research on the THz spectroscopy of materials and liquids on-chip. We conclude with an outlook on the field and highlight promising new directions. This chapter is meant to be an introduction and a general guide to this emerging field for new researchers interested in on-chip THz studies.

“…The dimensions of the CPW line are W s = 5 mm, g = 0.3 mm, W g = 25 mm, L CPW = 53.5 mm, L A = 71.5 mm, L t = 120 mm and the impedance of the CPW line is 50 Ω. CPW with tapered ground planes is used for mode conversion from CPW Quasi TEM mode to Goubau TM surface wave mode. CPW with tapered ground planes can efficiently excite surface wave mode along the Goubau line . Dimensions of inverted V‐shapes are optimized in such a way that the radiation from all the V‐shaped unit cells add in phase along the end‐fire direction.…”

This article proposes a simple and low profile planar Goubau line based end‐fire antenna. End‐fire radiation is achieved by modifying the Goubau line into inverted periodic arrangement of V‐shaped unit cells. Designed prototype is simulated and verified experimentally. Both the simulated and measured results are in good agreement. Proposed antenna radiates toward end‐fire direction between 7.8 and 8.3 GHz. The maximum gain of the antenna is obtained around 7.2 dBi. The average efficiency is observed 70% over the entire operating bandwidth. Proposed end‐fire antenna has a single metallic layer with simple configuration which is easy to fabricate and also easy to integrate with other electronics circuits. The proposed antenna can be used for satellite and RADAR applications.
