| Summary: | 碩士 === 國立中正大學 === 光機電整合工程所 === 96 === In this thesis, we have proposed a near field coupling micro-strip-line that will use non-contact coupling method to transmit RF electrical signal. Usually, the non-contact coaxial axis coupling method is used to transmit RF electrical signal by ring-shape micro-strip-line in transmitting end and receiving end. But the area of the ring-shape micro-strip-line is oversized and it is easy to produce the dislocation situation. Therefore, we used non-contact side coupling method to transmit RF electrical signal. In addition to, we used spiral-shape micro-strip-line to solve the dislocation problem.
The experiment results indicate the design of the meander-arc-shape micro-strip-line has return loss about is -40.4dB when the coupling distance is 1mm. In addition to, we compared spiral-shape micro-strip-line, ring-shape micro-strip-line and meander-arc-shape micro-strip-line on the dislocation experiment. The results indicate that the receive sensitivity of the ring-shape micro-strip-line had been changed from -20.664dB at zero-displace to -7.4873dB at 1mm displace. The receive sensitivity of the meander-arc-shape micro-strip-line had been changed from -27.187dB at zero-displace to -5.123dB at 1mm displace. The receive sensitivity of the spiral-shape micro-strip-line had been -10dB at 1~2mm displaces..
