  • Abstract The electronic industry PCB circuit design of product . The conventional signal-end transmission working on low speed in design engineer knowledge. The differential transmission line used in circuit is very popular application. The Advantages of differential transmission line are of fast transmission speed , immunity against electromagnetic interference, But the drawback is necessary to support 2 symmetry characteristic transmission line need same impedance and equalize propagation delay, the differential signal will not distortion and function down.
    But electronic industry product and PCB size is very small of specification for cost down . A lots component will mounting on PCB. It will reduce differential transmission space and path to straight connect with component or chip input . How to meet and support 2 symmetry characteristic transmission line need same impedance and equalize propagation delay . In this thesis we will find out solution.
    The object of this thesis is to propose a method for compensate as un-desired phase delay cause by unequal-length differential transmission lines. The propagation delay of a bend of differential transmission lines can be improved by disposing structure to the unequal length differential transmission lines. In this thesis release method is added transmission line into bend of transmission line two side . It will coupling two line and cause inductor and capacitor effect of lump circuit structure to improved unequal length differential transmission propagation delay problem. We use CST simulation software to simulate 90° find propagation delay problem and try to find some technique of solution to solve problem. Than use TDR to extract lump element into AWR program from bend of differential transmission line fixture and added line into bend of differential transmission line fixture also AWR program simulation time delay of result .  
    Finally we use oscilloscope to measurement all fixture and compare with simulation data. We are not consider UC-PBG and Meander line additional method because complex structure and high cost issue not good for electronic industry product usable.
