Computer Aided Design Of Microstrip Taper Lines
MetadataShow full item record
This work presents an accurate computer aided design (CAD) for niicrostrip taper lines in the microwave range of frequency. This CAD considers all design parameters affecting the characteristics of the line for different terminal impedances. The CAD takes into consideration the dispersion of effective permittivity at high frequency , different substrates materials, different shape ratios (w/h) and metalization thickness. The CAD is designed based on accurate formulas to obtain the matching requirements forany section. Evaluation of the reflection coefficient takes into account the variation of effective permittivity with line width and frequency, and then a modified reflection pattern is applied to obtain the optimum bandwidth for the tapered line. Restrictions for accurate calculations of the effective permittivity and the characteristic impedance at high frequency are underlined.
