Abstract :
We report a new dispersion model for shielded microstrip lint in the range 1⩽W/h1⩽10, 2⩽h2/h1, 0⩽f⩽20 GHz. Model has maximum deviation within 4% against the result of SDA. It has average of maximum deviation within 3.23%. Method is based upon reduction of shielded microstrip line into an equivalent open microstrip line with virtual permittivity which is a function of width of line, shield height and frequency. Over this equivalent virtual substrate Kirchning-Jansen dispersion model has been used. The present model is useful for fast interactive CAD, on the desk top computer
