Abstract: In this article, the methodology for the design of broadband impedance transformers is presented. The design of a set of Binomial impedance transformers with different operating frequency and dielectric characteristics is performed. These impedance transformers operate over frequency range from 1 to 2.8 GHz with a reflection coefficient Γ_m=0.05. The dielectric materials used were Duroid substrate and FR4 substrate, Duroid substrate has dielectric constant εr = 2.2 and thickness of substrate 1.27 mm and for FR4 substrate dielectric constant is $$ε_{r} = 4.4$$ and thickness of substrate 1.544 mm. The matching networks were simulated by ADS. Proposed matching networks can be used for UWB communication applications.
