    摘要: The tubular slot-mode antenna includes an array of slot antenna units carried by a tubular substrate, e.g. a cylindrical substrate, and each slot antenna unit having a pair of patch antenna elements arranged in laterally spaced apart relation about at least one central feed position. Adjacent patch antenna elements of adjacent slot-mode antenna units have respective spaced apart edge portions with predetermined shapes and relative positioning to provide increased capacitive coupling therebetween. The array of slot-mode antenna units may define a plurality of ring-shaped slots coaxial with an axis of the tubular substrate, and a feed arrangement may be coupled thereto to operate the array of slot-mode antenna units in an endfire mode.

    摘要: A phased array antenna includes a substrate, and an array of dipole antenna elements are on the substrate. Each dipole antenna element includes a medial feed portion, and a pair of legs extending outwardly therefrom. Each dipole antenna element further includes a passive load, and a switch connected thereto for selectively coupling the passive load to the medial feed portion so that the dipole antenna element selectively functions as an absorber for absorbing received signals while the passive load dissipates energy associated therewith.

    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 dual-polarization antenna with a slot pattern can produce vertical polarized energy near the horizon and can scan to near grazing angles. The dual-polarization, slot-mode antenna includes an array of dual-polarization, slot-mode, antenna units carried by a substrate, and each dual-polarization, slot-mode antenna unit having at least four patch antenna elements arranged in spaced apart relation about a central feed position. Adjacent patch antenna elements of adjacent dual-polarization, slot-mode antenna units have respective spaced apart edge portions defining gaps therebetween. Capacitive coupling plates are adjacent the gaps and overlap the respective spaced apart edge portions to provide increased capacitive coupling therebetween.

    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).
