Apparatuses and methods are provided including radome designs with tailorable through thickness reinforcement (TTR) or transverse members that increase mechanical durability of the reinforced radomes against an applied forces while providing desired radar transmissive performance matched to a particular environment. Embodiments provided allow for greater mechanical durability while maintaining sensitive RF performance across the entire structure. TTR in the embodiments include composite rods, fibers, fiber bundles, tows, or a combination of these options. The TTR can be placed through the core or both the skins and the core, and the TTR can be continuous threads of materials.

A broadband stacked multi-spiral antenna array comprising two or more spiral antennas with a dielectric layer having a generally uniform thickness positioned between each pair of stacked antennas, which are all center-fed and in-phase. The antenna array may be embedded in a non-conductive material, such as fiberglass embedded in a resin, a honeycomb core sandwich, or structural foam, that may be used to form a structural element of a mobile platform. The structural element may include a via providing a pathway for coaxial cables. If two structural elements are hatch covers on the port and the starboard sides of an aircraft, the use of a stacked multi-spiral antenna array in each structural element provides two roughly hemispherical coverage patterns which together provide an omni-directional coverage pattern. The stacked multi-spiral antenna array may also include a reflecting cavity placed at the bottom of one of the spiral antennas.

An aerial device for a vehicle, particularly an aircraft, includes an aerial arrangement and a lens, which includes a first lens area, made of a first material with a first dielectric constant, overlapping the aerial arrangement and a second lens area, made of a second material with a second dielectric constant, overlapping the first lens area, with the second dielectric constant being smaller than the first dielectric constant, and wherein the second lens area extends in a longitudinal direction and in a curve in respect of a vertical direction oriented transverse to the longitudinal direction.

An antenna assembly includes a circularly polarized antenna housing configured to mount to a mounting surface. The antenna assembly also includes a vertical antenna housing having a first end proximate to the circularly polarized antenna housing, as well as a distal end extending normally from the circularly polarized antenna housing.

A mechanically steered, horizontally polarized, directional antennae for aerial vehicles, such as UAVs. The antenna system can include a planar substrate with a horizontally polarized antenna embedded therein. A rotation member, on one end, can be attached to the planar substrate, and can extend from an external surface of the aerial vehicle. An actuator can be coupled to the rotation member to rotate the rotation member. A communication controller of the aerial vehicle can control the actuator to beam horizontally polarized radiofrequency (RF) waves to a target receiver or receive a wave front from a target transmitter.

Aircraft antenna fairing assemblies include a fairing shell and connection components for positionally fixing the fairing shell to airframe structure of an aircraft. The connection components may comprise a guide assembly having a guide head and a receiver defining a guide channel for receiving the guide head therewithin, and a latch assembly for latching the fairing shell to the airframe structure of the aircraft. The receiver of the guide assembly may define a generally C-shaped or generally U-shaped channel for receiving the guide head therewithin.

A radio frequency sensor module adapted for mounting a vehicle exhaust system structure. A bracket on the module includes a first mounting ear defining a first through aperture. A printed circuit board is coupled to the bracket. A cover defines an opening and an interior cavity in communication with the opening. The bracket and the cover are coupled together in a relationship with the printed circuit board extending through the opening in the cover and into the interior cavity of the cover and the first and second mounting ears in an abutting and overlying relationship. A mounting bolt extends through the respective first and second through apertures in the respective first and second mounting ears for securing the radio frequency module to the housing of a vehicle exhaust system.

In some embodiments, an antenna may include a plurality of reflectarray tiles and a frame including a plurality of frame elements coupled electrically and mechanically. The frame may be configured to conform to a shape of a surface. Each frame element may be configured to receive one of the plurality of reflectarray tiles. In some aspects, the plurality of reflectarray tiles may be illuminated directly or indirectly by a feed.

Aspects of the present disclosure generally relate to antenna structures suitable for vehicles, such as aircraft.
