ABSTRACT:
A continuously variable quarter-wave transformer (103) including a quarter-wave element (110). The quarter-wave transformer has a characteristic impedance and is at least partially coupled to a fluidic dielectric (108). A controller (136) is provided for controlling a composition processor (101) which is adapted for dynamically changing a composition of the fluidic dielectric (108) to vary the permittivity and permeability in response to a control signal (137). The permeability and permittivity can be varied together to maintain approximately constant impedance and length in wavelengths at different operating frequencies, or to vary impedance and maintain constant length at a given frequency. The quarter-wave transformer (103) can be coupled to a solid dielectric substrate material. A plurality of component parts can be dynamically mixed together in the composition processor (101) responsive to the control signal (137).
