Abstract
  • The exponentially tapered, nonuniform transmission' line, applied as an impedance transformer, is analyzed and modified. The analysis develops an expression for the input reflection coefficient that has the magnitude and phase as distinct functions. This allows ease in comparing the approximate and exact solutions and in developing the S-parameters for the taper. The modification is a slight change in the taper's shape that yields a significant reduction in the passband reflection coefficient (a tapered line is an impedance-transforming, high -pass filter) with only a slight increase in the taper's length. This modification is accomplished without sacrificing the exponential line's simple, closed-form expressions for both the reflection coefficient and the variation of impedance along the taper. These expressions are subjected to experimental verification.
