| With the rapid development of modern electronic and communication technologies, the data transfer rate between circuits, chips or devices is faster and faster. The requirement of the high-speed interconnect technologies is increasingly high. Traditional high-speed interconnect structures such as micro-strips and strip-lines, and so on, have severe loss and crosstalk in high-frequency range, which affect signal integrity in signal transmission. It can’t meet modern high-speed circuit requirements, therefore developing new high-speed interconnect technology is urgently needed.Half-mode substrate integrated waveguide(HMSIW) is evolved from substrate integrated waveguide(SIW). It has similar propagation characteristics and advantages to SIW, but only half size and doubles of single-mode operation bandwidth of SIW. Substrate integrated coaxial line combines the advantages of coaxial line and planar transmission line. it has good shielding and non-dispersive properties, as well as a wide main-mode bandwidth.The structure and propagation characteristics of HMSIW are first analyzes and its design method is summarized in this thesis. A HMSIW structure with 17.6GHz bandwidth is designed, simulated and tested. To transmit high-speed signals with HMSIW, an interconnection system and a QPSK modulation and demodulation system are proposed. The simulation, implementation and test of the HMSIW-based systems are made and compared with the SIW-based system. The interconnection system based on HMSIW enables 7.5Gbps data transmission, which is 1.5 times rate of mixing system based on SIW; the QPSK modulation and demodulation system based on HMSIW achieves 15 Gbps signal transmission, which is 1.5 times rate of the QPSK modulation and demodulation system based on SIW. Finally, the structure and propagation characteristics of substrate integrated coaxial lines are analyzed, and its design method is given. The substrate integrated coaxial line with 38 GHz operating bandwidth is designed and simulated. |
