摘要： The slot-mode antenna includes an array of slot antenna units carried by a substrate, and each slot antenna unit has 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 include respective spaced apart edge portions defining gaps therebetween, and a capacitive coupling layer or plates overlap the respective spaced apart edge portions to provide increased capacitive coupling therebetween. The capacitive coupling layer may include continuous or periodic capacitive coupling plates along each gap defined by the respective spaced apart edge portions.

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： Method and apparatus for feeding a compact main reflector of an RF antenna on a plurality of spectrally offset frequency bands. The method can include the steps of forming a focal ring for a main reflector (304) by positioning an RF source (301) at a first frequency within a first frequency band in the far field relative to a shaped non-linear surface of revolution so that the shaped non-linear surface of revolution forms a subreflector (302). A second focal ring can be formed for the main reflector (304) by positioning a second RF source (300) in the nearfield of the shaped non-linear surface of revolution.

摘要： An antenna feed system includes a plurality of RF horn antennas (201, 202) for operating on a plurality of RF frequency bands. A first one of the feed horns (202) can have a boresight axis and is configured for operating at a first one of the frequency bands. A second one of the feed horns (201) is positioned coaxially within the first one of the feed horns (202) and is configured for operating at least at a second one of the frequency bands. Further, the first one of the feed horns (202) is a corrugated horn that has a plurality of corrugations (204) formed on an interior surface defining a profile. The profile extends substantially from a throat (205) of the first feed horn and along a tapered portion of the first feed horn. The profile substantially minimizes an interaction of the corrugations with the second feed horn.

A first feed (301, 403) includes a first feed horn (301) and a first sub-reflector (403), which are positioned spaced apart from each other at respective locations along a boresight axis of the main reflector. The locations are selected so that the first feed horn and the first sub-reflector share a commonly located first phase center (401). A second feed (302, 404) designed for operation on a second RF frequency band includes a second feed horn (302) and a second sub-reflector (404), each positioned at a location along the boresight axis of the main reflector so that they share a commonly located second phase center.

摘要： A ring focus antenna and method of using same. The ring focus antenna can have a main reflector of revolution shaped as a non-regular paraboloid about a boresight axis of the antenna. A sub-reflector/feed pair is provided comprising a sub-reflector of revolution shaped as a non-regular ellipsoid having a ring-shaped focal point about the boresight axis. A feed element is installed at a feed element location separated spaced from a vertex of the sub-reflector on the boresight axis of the antenna. The main reflector is adapted for operation with multiple sub-reflector/feed pairs having a coupled configuration, and multiple sub-reflector/feed pairs having a decoupled configuration (i.e. classical optical dual reflector system). The main reflector is operable at a plurality of spectrally offset frequency bands. For example, the antenna can be designed for operation over C-band, X-band, Ku-band, and Ka-band.
