註釋The fifth-generation (5G) technology is known as the new generation of mobile data connectivity and wireless communication systems. It will provide breakneck broadband speeds and will have enough capacity to perform every function without a decrease in connection speed, no matter how many peoples are connecting into the network at the same time. One of the main benefits of 5G technology over the fourth-generation (4G) technology is not only its speed of delivery, between 10Gbps and 100Gbps, but also the latency. Specifically, the underemployed spectrum in the millimeter-wave frequency band (30-300 GHz) might be seen as a potentially profitable solution for achieving the aforementioned purposes. However, the development of next generation of mm-wave high performance circuits and systems is requiring low-cost fabrication process, small area, low consumption and 3D integration. In this context, CNT-based technology has attracted a lot of attention and could be considered as an excellent candidate for designing the mm-wave circuits due to its outstanding characteristics as compared to the other materials. Therefore, in this thesis, in the framework of the ANR project TRICOT, CNT will be considered as particular materials to design and develop a new 3D integration technology and concept dedicated to future applications in mm-wave interconnects and circuits.The work achieved in this PhD thesis was principally concentrated in two directions. The first one involves in the utilization of CNT technology to design the AF-SIW circuits for mm-wave applications in E-band. The second direction concerns the utilization of the slow-wave concept for the miniaturization of AF-SIW circuits designed for the RF applications based on both conventional PCB and CNT technologies. In both subjects, the proposed structures were detailed, then theoretical analyses were developed, and simulation and measurement results were presented. The retro-simulations were also realized when needed, which permitted to validate the proposed concepts by proofs of concept.In the first chapter of this thesis, an overview concerning the techniques utilized to design and fabricate BM was introduced in both RF and mm-wave frequency bands. Miniaturization techniques and low-loss air-filled technology were also presented in this chapter. The second chapter introduced in detail the physical properties of carbon nanotubes. Due to its outstanding properties as compared to other materials, CNTs could be considered as a potential material for next-generation electronics applications in order to replace classical metal-based structures. The analytical and electromagnetic modeling of CNTs were also introduced in this chapter, based on the work performed at XLIM laboratory, Limoges, France. Thanks to the bulk model, the CNT-based devices are designed more easily, and with accuracy. In the third chapter, a detailed description of AFSIW waveguide based on CNT technology was presented. Furthermore, the CNT technology used to design the AFSIW waveguide was also applied to the design of 0-dB and 3-dB couplers based on the short-slot topology with the same concept. In the fourth chapter, AF-SW-SIW design blocks based on CNT technology designed at 28 GHz for RF applications was investigated and presented. Finally, the last chapter was dedicated to the detailed description of PAF-SW-SIW waveguide based on conventional PCB technology designed at 28 GHz for RF applications.
