In this letter, a grounded coplanar waveguide-to-microstrip (GCPW-to-MS) transition without via holes is presented. The transition is designed on a PET® substrate and fabricated using inkjet printing technology. To our knowledge, fabrication of transitions using inkjet printing technology has not been reported in the literature. The simulations have been performed using HFSS® software and the measurements...
In this work, a pulse shaper in coplanar technology intended for the unlicensed band up to the THz region is designed, fabricated, and measured. This broadband frequency range is of great interests as it offers very high data rate communication in local area networks. The technique employs tailored coplanar lines that have been designed using an exact analytical series solution of the synthesis problem...
In this communication, we study the effect of the position of SRR on the resonance frequency of the planar circuit. The idea is to better control the position of SRR along the Planar Goubau Line (PGL) in order to attain maximum rejection. This result is important for the design of terahertz circuits. As a demonstration of the flexibility and scalability of the designs, we show experimental results,...
For terahertz microscopy, we propose an original approach with Planar Goubau Lines (PGL) by taking advantage of the confinement around the metallic strip. The idea is to obtain an alternative to the illumination by free space wave. The structure is fabricated on a thin high resistivity silicon substrate and it is composed of two CPW-PGL transitions, two bendings and a coupling region between the two...
Low loss broad band transmission lines are of great interest for terahertz applications. To overcome high losses, Planar Goubau Lines (PGL) have been designed and fabricated on high resistivity silicon substrate. The measured loss level is typically 1dB/mm around 250GHz. The transitions are also extremely efficient for CPW-to-PGL conversion. The loss level depends on certain parameters such as length...
The electromagnetic field around Planar Goubau transmission Line (PGL) offers the possibility of tailoring the response of metamaterials components such as single or multi-micro resonators type. In this paper, we suggest a novel design of filter based on PGL coupled with micro split rings resonators (SRR). The frequency selectivity of resonant-type metamaterial transmission lines suggests their application...
