Synthesis of Impedance Transformers for Super-Wideband Two-Section Antenna Arrays

详细

Approximation of microwave transmission line is used to study synthesis of impedance transformers for super-wideband two-section antenna arrays. Several variants of a complicated nonmonotonic impedance transformer (two-section array that represents two monotonic or nonmonotonic and monotonic transformers) are considered. Parameters of step transformers are synthesized in the approximation of small coefficients of reflection from steps of characteristic impedances of the transmission line. The method for synthesis is extrapolated to continuous transformers. Variants of construction of two-section antenna arrays are compared, and the error of the approximate synthesis method is estimated.
