Abstract This paper presents a novel transmission line with variable characteristic impedance. A tunable impedance transformer using this line is fabricated and measured. The impedance transformer can be electronically varied from 10Ω to 65Ω in a 50Ω environment at the center frequency of 900 MHz. © 2005 Wiley Periodicals, Inc.
