More particularly, the first and second phased array antennas may include respective first and second arrays of dipole antenna elements thereon, wherein each dipole antenna element may include a medial feed portion and a pair of legs extending outwardly therefrom.

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.

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： A phase delay line (110). The phase delay line can include an RF transmission line (111) and a fluid channel (109) having a serpentine configuration. The transmission line can be coupled to a solid dielectric substrate material (102), for example a substrate formed from a low temperature co-fired ceramic material. The fluid channel can be coupled to the RF transmission line along at least a portion of a length of the transmission line. A phase delay of the RF transmission line can be selectively varied by adjusting a distribution of the fluidic dielectric (130) present within the fluid channel. Similarly, the phase delay of the RF transmission line also can be maintained constant as an operational frequency of the RF transmission line is varied.
