    摘要: A variable RF filter (102) which includes one or more filter elements (104,106). The filter elements (104,106) can be formed from a structure selected from the group consisting of stripline, microstrip, and buried microstrip. A fluid dielectric (108) and a fluid control system (150) for selectively moving the fluid dielectric from a first position to a second position are provided. In the first position, the fluid dielectric (108) is electrically and magnetically coupled to the filter elements (104,106) to produce a first filter response. In the second position, the fluid dielectric (108) is electrically and magnetically decoupled from the filter elements (104,106) to produce a second filter response distinct from the first filter response. The first position can be defined by a bounded region located adjacent to the filter elements (104,106) and the second position is defined by a fluid storage reservoir (170).

    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. The fluid dielectric (108) is electrically and magnetically decoupled from the transmission line stub (102) in a second position to produce a second tuned response which is distinct from the first tuned response.

    摘要: A reflector antenna system may include an arc-shaped antenna reflector defining a first antenna beam, and a phased array antenna positioned in the first antenna beam including first and second arrays of antenna elements coupled together in back-to-back relation. The first array may face the antenna reflector, and the second array may face away from it. A controller switchable between a reflecting mode and a direct mode may be connected to the arrays. The controller, when in the reflecting mode, may cause back-to-back pairs of first antenna elements from the arrays to define a feed-through zone for the first antenna beam, and cause second antenna elements in the first array to define a first active zone for the first antenna beam. Furthermore, when in the direct mode, the controller may cause antenna elements in the second array to define a second active zone for a second antenna beam.
