Abstract: An antenna assembly includes a first dielectric material, a ground plane above the first dielectric material, and two or more patch antennas above the ground plane. In an example, the ground plane has a first aperture slot, and a second aperture slot that is non-intersecting with the first aperture slot. The antenna assembly further includes a second dielectric material separating the two or more patch antennas from the ground plane. In an example, the first dielectric material comprises a printed circuit board (PCB). In some examples, the ground plane and the two or more patch antennas are manufactured using additive manufacturing techniques (such as three-dimensional printing techniques), and in some such examples, the second dielectric material includes dielectric foam. For example, the dielectric foam supports the two or more patch antennas above the ground plane.

Abstract: An antenna assembly includes at least one conductive dipole arm and an adjacent conductive wall (“H-wall”), which enables efficient radiation from the conductive dipole arm without added losses. A single-ended antenna feed is configured to receive a single-ended signal. The antenna assembly further includes a ground plane and a conductive dipole arm in planar alignment with a surface of the ground plane. The conductive wall is electrically coupled with the ground plane and has an end adjacent to, and physically separate from, the conductive dipole arm, an axial length of the H-wall being orthogonal to the ground plane. The antenna assembly further includes a feedline electrically coupled with the conductive dipole arm and the single-ended antenna feed.

Abstract: An antenna assembly includes a ground plane having a first aperture slot and a second aperture slot. The first and second aperture slots are non-intersecting and substantially symmetrical with each other about an imaginary plane of symmetry that divides the ground plane into two substantially symmetrical halves, and that is orthogonal to the ground plane. The antenna assembly includes a first patch antenna above the ground plane, and a second patch antenna above the first patch antenna. The first patch antenna is separated from the ground plane, and the second patch antenna is separated from the first patch antenna. The imaginary plane also divides the first patch antenna into two substantially symmetrical halves, and divides the second patch antenna into two substantially symmetrical halves. A first feed line and a second feed line are at least in part below the first aperture slot and the second aperture slot, respectively.

Abstract: A stacked patch antenna is expandable from a thinner stowed configuration in which the gaps between the conductor layers are reduced, to a thicker deployed configuration in which the gaps are expanded to their required dimensions. The expansion mechanism can include rotation of threaded rods, pneumatic expansion of telescoping rods, and/or injection of a gas, a chemical sublimate, and/or an expandable foam into the gaps. In embodiments, the stowed thickness of the antenna can be approximately equal to the sum of the thicknesses of the conductor panels. In some of these embodiments high dielectric layers are not included. In other of these embodiments high dielectric layers are formed by filling gaps with a high dielectric foam. Embodiments implement aperture coupling to the stacked patch antenna. An array of the stacked patch antennae can be folded about a satellite until deployment, and can be planar when unfolded and deployed.

Abstract: An antenna assembly includes a first flexible layer including a conductive ground plane on a first layer of dielectric material, and a second flexible layer including a first array of conductive patches on a second layer of dielectric material. The antenna assembly further includes a second array of conductive patches on a third layer of dielectric material. The first, second, and third flexible layers are rollable or foldable, to provide a stowed position for the antenna assembly and a deployed position for the antenna assembly. In an example, the first array of conductive patches includes at least a first patch and a second patch, and the second array of conductive patches includes at least a third patch and a fourth patch. In the deployed position, the first patch is above the third patch and the ground plane, and the second patch is above the fourth patch and the ground plane.

Abstract: A method of manufacturing an antenna assembly includes additively manufacturing an element that is monolithic and that includes (i) a ground plane, (ii) a patch above the ground plane, and (iii) a structure having a lower end in contact with the ground plane and an upper end in contact with the patch. The method further includes applying a dielectric material between the ground plane and the patch. In an example, the dielectric material is dielectric foam. The method further includes removing a section of the ground plane around the lower end of the structure, such that the structure extends through the ground plane and not in contact with the ground plane. The method further includes connecting an inner conductor of a coaxial cable connector to the lower end of the structure, and an outer portion of the coaxial cable connector to the ground plane.

IPC: H01Q9/04
Abstract: An antenna assembly includes a ground plane including conductive material, and a dielectric material above the ground plane. A patch antenna is on the dielectric material. In an example, a plurality of features extends from an upper surface or a lower surface of the dielectric material and within the dielectric material, wherein the plurality of features comprises voids filled with gas or are vacuum. Additionally, or alternatively, the dielectric material is doped with a dopant. In an example, the antenna assembly further includes a first aperture and a second aperture on the ground plane and below the patch antenna, and another dielectric material below the first and second apertures. In some such cases, a first feed line is below the first aperture, and a second feed line is below the second aperture.

Abstract: A method of manufacturing an antenna assembly includes additively manufacturing an element that is a monolithic structure and that includes (i) a ground plane including one or more aperture slots, (ii) a patch antenna above the ground plane, and (iii) a sacrificial support feature to support the patch antenna above the ground plane. The method further includes applying a dielectric material between the ground plane and the patch antenna. In an example, applying the dielectric material between the ground plane and the patch antenna includes providing a dielectric foam between the ground plane and the patch antenna, where the dielectric foam at least in part supports the patch antenna above the ground plane. The method further includes removing at least a section of the sacrificial support feature, such that any remnant of the support feature does not physically couple the ground plane to the patch antenna.
