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 an antenna feed, a ground plane, a first antenna element, a second antenna element, and a shorting post that is shared between the first and second antenna elements. The first antenna element includes a first conductive dipole arm in planar alignment with a surface of the ground plane and a second conductive dipole arm in planar alignment with the surface of the ground plane and adjacent to the first conductive dipole arm. The second antenna element includes a third conductive dipole arm in planar alignment with the surface of the ground plane and adjacent to the second conductive dipole arm, and a fourth conductive dipole arm in planar alignment with the surface of the ground plane and adjacent to the third conductive dipole arm. The shorting post is in electrical communication with the ground plane, the second conductive dipole arm and the third conductive dipole arm.

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: An antenna element suited for direction finding (DF) with omni-directional radiation patterns utilizing a pair of chevron slots fed using a ridged waveguide magic tee (magic-t) and connected microstrip probes. The provided antenna element provides improved performance, power handling, and improved bandwidth compared to current monocone and/or slot antenna elements. The antenna element may be further realized utilizing additive manufacturing processes in combination with standard metal and polymer production techniques.

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.

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.
