Abstract:

Dielectric fill features may have a significant effect on the characteristics of both the cable and microstrip transmission lines. It is necessary to provide proper characteristic impedance of microstrip transmission lines to create a multi-layer printed circuit boards with digital, analog and RF circuits. The authors simulate the impact of the planar location of two conductors in a dielectric material above an ideally conducting plane on the board delays per unit length of transmission-line modes. The simulation showed the dependency of even and odd modes and their differences on the distance between the conductors during the change in the depth of immersion of conductors into the dielectric material. The behavior of obtained dependencies was explained. It was discovered that the difference of board delays changes sign and reaches high values (from – 0.8 to 1.5 ns/m) with close coupling. Obtained results can be used for further research in the field of electronics. In particular, for model filtering development based on microstrip lines. This will reduce the level of the ultrashort pulses problem.
