摘要： A dual-polarized, stub-tuned, proximity-fed, stacked patch antenna includes a ground plane layer and a dielectric substrate overlying the ground plane layer. An active patch antenna element is disposed on the dielectric substrate. A parasitic patch antenna element is supported in spaced relation to the active patch antenna element. Dual feed lines are spaced from and field-coupled to the active patch antenna element. Each feed line has a tuning stub for producing a distributed antenna resonance. The dual feed lines are configured to provide dual polarization and minimize coupling between the feed lines. The feed lines are positioned substantially orthogonal to each other to provide orthogonal linear polarizations. Each feed line includes a feed line tip that extends towards the center of the active patch antenna element and spaced from each other to minimize tip-to-tip coupling. Each feed line tip includes a 90 degree bend.

摘要： The invention concerns a method and apparatus for reducing mutual coupling among adjacent planar antenna radiating elements in an array. The elements can be positioned adjacent to one another in a standard geometric array configuration. A circumferential conductive metal line is provided in the plane of each element at an outer perimeter thereof. The conductive metal line is electrically connected to a ground potential. The ground plane potential is preferably provided by a ground plane reflector over which the antenna elements are suspended. The conductive metal line can be connected to the ground plane reflector by one or more ground posts extending between the conductive metal line and the ground plane reflector.

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 redirecting feedthrough lens antenna system may include first and second phased array antennas coupled together in back-to-back relation. 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. The system may also include a respective phase shifter connected between each pair of back-to-back dipole antenna elements of the first and second dipole antenna arrays. Furthermore, a controller may be included for cooperating with the phase shifters to cause a signal received by the first phased array antenna at a first angle to be transmitted from the second phased array antenna at a redirected second angle different from the first angle.
