    摘要: Method and apparatus for producing a variable delay for an RF signal. The method can include the step of propagating the RF signal along an RF transmission line, coupling a fluidic dielectric to the RF transmission line, and dynamically changing a composition of the fluidic dielectric to selectively vary its permittivity in response to a time delay control signal. The method can also include the step of dynamically changing a composition of the fluidic dielectric to vary its permeability. The permittivity and the permeability can be varied concurrently in response to the time delay control signal. In a preferred embodiment the method can include selectively varying the permeability concurrently with the permittivity to maintain a characteristic impedance of the transmission line approximately constant.

    摘要: Method for controlling an input impedance of an antenna (100). The method can include the steps of coupling RF energy from an input RF transmission line (106) to an antenna radiating element (102) through an aperture (112) defined in a ground plane (110). For example, the aperture (112) can be a slot and the radiating element (102) can be a patch type element. The input impedance can thereafter be controlled by selectively varying a volume or a position of a conductive fluid (128) disposed in a predetermined region between the RF transmission line and the antenna radiating element. The volume of conductive fluid (128) can be automatically varied in response to at least one control signal (132).

    摘要: The present invention relates to a variable tuned transmission line stub (102). The transmission line stub (102) has an input (104) at one end, an electrical length, and a termination at an opposing end (122). A fluid dielectric (108) is electrically and magnetically coupled to the transmission line stub (102) in a first position to produce a first tuned response.
