An antenna includes antenna elements, an antenna feed assembly and at least one integrated circuit adjacent the antenna feed assembly on a side thereof opposite the antenna elements. The at least one integrated circuit is connected to the antenna elements via the antenna feed assembly. The antenna feed assembly includes a conductive base plate spaced from the antenna elements, and has feed openings therein. Spaced apart conductive posts are integrally formed with the conductive base plate as a monolithic unit, and extend outwardly therefrom toward the antenna elements. Each conductive post has at least one passageway therethrough aligned with at least one respective feed opening to define at least one antenna feed passageway. A respective elongated feed conductor extends through each antenna feed passageway.

A phased array antenna includes a substrate having a first surface, and a second surface adjacent thereto and defining an edge therebetween. A plurality of dipole antenna elements are on the first surface, and at least a portion of at least one dipole antenna element is on the second surface. Each dipole antenna element includes a medial feed portion and a pair of legs extending outwardly therefrom. Adjacent legs of adjacent dipole antenna elements on the first and second surfaces include respective spaced apart end portions having predetermined shapes and relative positioning for providing increased capacitive coupling between the adjacent dipole antenna elements.

A wideband phased array antenna includes an array of dipole antenna elements on a flexible substrate. Each dipole antenna element has a medial feed portion and a pair of legs extending outwardly therefrom, and adjacent legs of adjacent dipole antenna elements have respective spaced apart end portions to provide increased capacitive coupling between the adjacent dipole antenna elements. Preferably, each leg has an elongated body portion, and an enlarged width end portion connected to an end of the elongated body portion. Thus, a phased array antenna with a wide frequency bandwith and a wide scan angle is obtained by utilizing tightly packed dipole antenna elements with large mutual capacitive coupling. Conventional approaches have sought to reduce mutual coupling between dipoles, but the present invention makes use of, and increases, mutual coupling between the closely spaced dipole antenna elements to prevent grating lobes and achieve the wide bandwidth.

An antenna includes a substrate including a ground plane and a dielectric layer adjacent thereto and at least one antenna unit carried by the substrate. The at least one antenna unit may include a plurality of adjacent antenna elements arranged in spaced apart relation from one another about a central feed position on the dielectric layer opposite the ground plane. The at least one antenna unit may also include an antenna feed structure including a respective coaxial feed line for each antenna element and a feed line organizer body having passageways therein for receiving respective coaxial feed lines.

A spaceborne hybrid antenna reflector for dual frequency band illumination of common spot beam coverage regions contains an interior solid reflector region, that is adjacent at its perimeter to a ring-shaped exterior dichroic reflector region and adjoined by a common backing structure. The solid interior region is reflective to RF energy at each of first and second spaced apart frequency bands, while the exterior dichroic reflector region is reflective at the first frequency band, but non-reflective at the second frequency band. This allows the hybrid reflector to realize the same beamwidth coverage for a transmitter operating at one frequency band and a receiver operating at the other frequency band. The backing support frame at the rear side of the reflector is electrically decoupled from the exterior dichroic ring.

A phased array antenna element includes an antenna support and two longitudinally extending radiating leg element supported by the antenna supports. The radiating leg elements are positioned in a straight v-configuration from the vertex to antenna element tips. Each radiating leg element has a low loss at the vertex to a high loss at the antenna element tips.

A phased array antenna element includes an antenna support and two longitudinally extending radiating leg elements supported by the antenna support and flared outward in a v-configuration from a vertex to antenna element tips. A resistive element is positioned on each radiating leg element and has a resistive value along the radiating leg elements from a low loss at the vertex to a high loss at the antenna element tips. The radiating leg elements are curved outward along their length and form a triangular configuration having a height that is about three times greater than the base.

The dual polarization antenna includes a substrate having a ground plane and a dielectric layer adjacent thereto, and at least one antenna unit carried by the substrate. The antenna unit includes four adjacent antenna elements arranged in spaced apart relation from one another about a central feed position on the dielectric layer opposite the ground plane. Preferably, diagonal pairs of antenna elements define respective antenna dipoles thereby providing dual polarization. The antenna unit also includes an antenna feed structure having four coaxial feed lines, each coaxial feed line including an inner conductor and a tubular outer conductor in surrounding relation thereto. The outer conductors have parallel adjacent ends joined together about an axis and are connected to the ground plane. The ends of the outer conductors are tapered and arranged so that portions thereof adjacent the axis extend further beyond the ground plane in the dielectric layer and toward the antenna elements. The inner conductors preferably extend outwardly from ends of respective outer conductors, through the dielectric layer and are connected to respective antenna elements adjacent the central feed position.
