The subject matter described herein relates to devices and methods for allowing satellite antennas to be shipped in a single flat package. These devices and methods have particular but not exclusive utility for satellite TV and Internet service installation.
Satellite antennas are known, and are used to deliver satellite TV and Internet services. They may additionally be used for navigation, meteorology, fleet management, deep space communication, and military purposes. However, such antennas are bulky and are generally assembled on-site at the time of installation, from components that ship in separate packages. This assembly process is difficult for consumers, time consuming for professional installers, and the shipping process is expensive and wasteful of packaging materials.
More specifically, for many current antenna systems, an installation process involves unpacking separately packaged components and then assembling the components into a desired from. The components often include a reflector, a backing structure assembly, a feed arm, and a low-noise block downconverter (LNB), along with assorted attachment hardware such as nuts, bolts, and screws. Often, the reflector may have a parabolic shape.
Further, once the components are unpacked, the reflector, feed arm and LNB are assembled into a finished form that is then attached to a mast or similar mounting structure. Commonly, an installation technician attaches the reflector to the backing structure by threading bolts through a set of through holes and then securing them in place with nuts. It is to be appreciated that an installer may include a licensed installation technician, an electrician, a home-owner, or otherwise (herein, an “installer”). In a typical example, four bolts are secured through four through-holes. Next, the LNB bracket is attached to the end of the feed arm using additional nuts, bolts, and screws. In a typical example, two bolts are secured through two through-holes, and two screws are secured into two threaded holes. The backing structure is then mounted to the mast, or to a roof, wall, railing, or other convenient attachment point. Finally, the installed antenna assembly is “peaked”, or precisely oriented toward a particular geostationary satellite or plurality of geostationary satellites, in order to maximize signal strength. Most of the time used to attach the antenna/backing structure assembly to the mast is spent installing the attachment hardware to hold everything together. The antenna systems are not preassembled due to their awkward size and the cost it would take to ship them. It is to be appreciated that such commonly used components, installation processes, and packaging approaches have numerous drawbacks, including risks of misalignment, time costs, packaging costs, and otherwise. Accordingly, needs exist for devices, processes, packaging approaches, and otherwise which address the forgoing and other concerns.
The information included in this Background section of the specification, including any references cited herein and any description or discussion thereof, is included for technical reference purposes only and is not to be regarded as subject matter by which the scope of the disclosure is to be bound.

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to limit the scope of the claimed subject matter. A more extensive presentation of features, details, utilities, and advantages of the lay flat antenna assembly, as defined in the claims, is provided in the following written description of various embodiments of the disclosure and illustrated in the accompanying drawings.
In accordance with at least one embodiment of the present disclosure, a collapsible or foldable antenna backing structure is provided which allows components of an antenna system to be pre-assembled at a factory, shop facility, or otherwise. Such components for an antenna system may include one or more of a reflector, a backing structure, a feed arm, an LNB or other radio frequency (RF) energy receiving device, hardware and other components. For at least one embodiment, the combined assembly for an antenna system may be shipped as one piece to an installer. For at least one embodiment, the combined assembly for an antenna system may be provided in a collapsed state which may fit into a single package, such as a substantially shallow or flat package.
For at least one embodiment, when an antenna system according to the present disclosure is desired for installation, the installer may remove the combined assembly from packaging, swivel the feed arm into place, engage a spring loaded locking pin, and proceed with attaching the antenna system to a mast or other mounting surface, device or structure. It is to be appreciated that the foregoing operations involve substantially fewer installation steps and commonly will save several minutes when compared to existing antenna installation procedures. Further, it is to be appreciated that shipping costs may also be substantially reduced, as the number of packages and total volume of packages will result in a smaller shipping volume, where the shipping volume is a combination of the total height, width, and depth of the packages used to otherwise provide the above-mentioned components. It is to be appreciated, a device may include a package containing a combined assembly of an antenna system in accordance with at least one embodiment of the present disclosure. Such a package may or may not include one or more LNB or other receiving components attached to a feed arm.
In accordance with at least one embodiment of the present disclosure, the backing structure may include as integrated therewith and/or be configured for use therewith a swivel plate. The swivel plate may be used between the feed arm and the backing structure and allows rotation of the former relative to the latter under controlled conditions. For at least one embodiment, a swivel plate may be riveted or may employ conventional hardware, such as nuts and bolts, to secure the feed arm to the backing structure while also permitting rotation about one or more axis. Having the connection between the feed arm and backing structure rotatable allows the antenna system or portions thereof to be pre-assembled at the factory, prior to shipment to the field. With this configuration, an installer may proceed by removing the antenna assembly from its protective packaging, rotating the feed arm into a desired position, secure the feed arm at its desired position, and place the assembly on a mast or other attachment point. It is to be appreciated, however, that one or more of these operations may occur in a different order or sequence of operations.
For at least one embodiment, the feed arm may be secured and/or “locked” into a desired operational position, for use, by use of a locking pin, tightening hardware, spring mechanism, or otherwise. Such locking mechanism(s) may be provided free-standing or integrated, in whole or in part, with one or more of the backing structure, feed arm, swivel plate, or otherwise.
Likewise, for at least one embodiment, the feed arm may be aligned, and/or locked, in a desired operational or non-operational position, at any time. It is to be appreciated that such an operational or non-operational position alignment and/or locking may be desirable during attachment of the antenna system to a mast, during shipment, repositioning, or otherwise. For at least one embodiment, locking of the feed arm into an operational position may occur after attachment of the antenna system to a mast or other mounting structure. Further, it is to be appreciated that by providing a rotatable feed arm, relative to the backing structure, time savings may be realized during assembly of the antenna system. Such time savings may often eliminate and/or reduce one or more time consuming steps of commonly pursued antenna installation processes today. Further, it is to be appreciated that for at least one embodiment of the present disclosure, the use of loose and/or separately packaged hardware commonly utilized to attach the reflector, feed arm, and otherwise to the backing structure can be reduced, and for at least one embodiment, eliminated.
Furthermore, current practices of attaching a reflector to a backing structure on-site often present a number of risks. Over-torqueing of bolts may distort the reflector, whereas under-torqueing may allow the reflector to become misaligned, to wobble under dynamic loads, to loosen itself, or to be more susceptible to damage. Furthermore, off-axis alignment of the feed arm at the time of in-field installation may result in radio-frequency (RF) energy not being directed properly reflected towards the LNB attached to a distant end of feed arm. It is to be appreciated, that when the feed arm and LNB extending therefrom are properly aligned relative to the reflector surface, a maximal amount of desired RF energy, transmitted by a satellite or other transmitting source and impinging on the reflector, is directed to the LNB and/or other receiving component(s).
It is to be appreciated, that the direction of the maximal of RF energy may include one or more beams of RF energy emitted from one or more sources and such multiple beams may be directed by the reflector to one or more separate, or the same focal points. The LNB and/or one or more receiving components, may be positioned at such one or more focal points. Given these and other considerations, it is to be appreciated that one or more embodiments of the present disclosure facilitate highly-accurate positioning of LNBs and/or other RF energy receiving components at desired focal point locations. As used herein, “highly-accurate positioning” of an LNB relative to a focal point of reflected RF energy from a reflector means that the actual positioning of the LNB relative to the desired positioning of the LNB is within +/−1.6 degrees of specifications.
Further, it is to be appreciated that, for at least one embodiment, attachment of one or more of a reflector, feed arm, LNB and/or other components to a backing structure may occur in a quality-controlled factory or other setting as part of the manufacturing and/or assembly process, as opposed to being completed in the field by an installer. Resulting quality, alignment accuracy, and consistency may result in less installation rework, less ongoing maintenance, longer antenna system operational life, and other savings in time, material, labor, packaging, shipment, and otherwise.
These descriptions are provided for exemplary purposes only, and should not be considered to limit the scope of any embodiment of the described lay flat antenna, assembly of such lay flat antenna, packaging of an antenna system, or otherwise. Certain features may be added, removed, or modified without departing from the spirit of the claimed subject matter.
As shown in
The LNB bracket 103 may be secured to the feed arm 101 with attachment hardware 107. Such attachment hardware 107 may include, but is not limited to, a threaded hole and a screw, a through hole, bolt, and nut, and other types of attachment hardware may be used, including but not limited to, pins, clips, rivets, welds, and other known attachment techniques and devices.
The feed arm 101 may be attached to the feed arm bracket 108. Any desired type of attachment hardware 107 may be utilized, such as those described above. For at least one embodiment, the feed arm 101 may be welded to the feed arm bracket 108. Attachment hardware, devices and/or techniques may be the same or may vary for the attachment of any antenna system component to another antenna system component.
The backing structure 100 may be designed to withstand static and dynamic loads for a given intended use environment. Such use environments may vary by topography, location, latitude, longitude or otherwise. Non-limiting examples of use environments include, but are not limited to, wind, hurricane, tornado, snow, ice, and other environments. For at least one embodiment, backing structure 100 is configured to withstand one or more given use environments, without breaking apart, becoming misaligned, or otherwise experiencing a failure in terms of performance, configuration, assembly or otherwise. For example, in order to comply with hurricane regulations in the United States state of Florida, the backing structure 100 may be designed to withstand winds of up to 155 miles per hour without breaking apart and releasing components or fragments as projectiles.
In accordance with at least one embodiment of the present disclosure, the addition of the swivel plate 105 between the feed arm 101 and the backing structure 104 facilitates rotation of the feed arm 101 relative to the backing structure 104. This configuration further facilitates configuring of the antenna system 100 for storage and shipping, and also facilitates the unfolding of the antenna system for installation. Further, the use of the swivel plate 105 for at least one embodiment, facilitates use of one or more assembly processes that may occur in a factory, shop, or other setting, while also removing the presently common process steps of on-site assembly of the antenna system by an installer.

Further, it is to be appreciated from the various views that when in the second configuration of entire antenna system 200 may fit into a single flat package of having dimensions L×H×W, with W now being dependent on the second width W2, which reduce packaging sizing and shipping costs. Furthermore, the antenna system 200 may be unfolded and locked into the first configuration by an installer by performing only the rotation of the feed art about the Y axis, which presumably and an untrained person could accomplish. Such ease of installation further facilitating cost savings from use of an embodiment of the present disclosure and further facilitating accurate and consistent installation of an antenna system 200 by such a non-skilled installer.
Based on design considerations, the components described above may be of substantially different shape than depicted in the Figures, while still operating in the same or an equivalent manner. The locking apparatus and any of the attachment hardware may include wing nuts, lock nuts, flat washers, spring-lock washers, serrated flanges, detents, or other equivalent attachment aids.
As will be readily appreciated by those having ordinary skill in the art after becoming familiar with the teachings herein, this disclosure solves a long-standing need in the satellite communications industry and other industries using directional antenna assemblies, by providing an antenna structure that is easily manufactured to consistent standards, as well as easily assembled and installed.
A number of variations are possible on the examples and embodiments described above. For example and as shown in
In some implementations, some or all fasteners may be eliminated by combining certain components as single units. It should further be understood that the described technology may be employed in other industries than satellite communications, and may be applied to non-satellite antennas including TV antennas, microwave and RF communication antennas, and acoustic listening devices.
All directional references e.g., upper, lower, inner, outer, upward, downward, left, right, lateral, front, back, top, bottom, above, below, vertical, horizontal, clockwise, counterclockwise, proximal, and distal are only used for identification purposes to aid the reader's understanding of the claimed subject matter, and do not create limitations, particularly as to the position, orientation, or use of the lay flat antenna assembly. Connection references, e.g., attached, coupled, connected, and joined are to be construed broadly and may include intermediate members between a collection of elements and relative movement between elements unless otherwise indicated. As such, connection references do not necessarily imply that two elements are directly connected and in fixed relation to each other. The term “or” shall be interpreted to mean “and/or” rather than “exclusive or.” Unless otherwise noted in the claims, stated values shall be interpreted as illustrative only and shall not be taken to be limiting.
The above specification, examples and data provide a complete description of the structure and use of exemplary embodiments of the lay flat antenna assembly as defined in the claims. Although various embodiments of the claimed subject matter have been described above with a certain degree of particularity, or with reference to one or more individual embodiments, those skilled in the art could make numerous alterations to the disclosed embodiments without departing from the spirit or scope of the claimed subject matter. For example, components may be made of many varied materials, and may be colored or patterned for aesthetic purposes or for ease of assembly. Additionally, instructions or indicators may be provided on the antenna system 200 itself, in the form of permanent or removable stickers or other markings, that teach or demonstrate the packing, assembly, or installation of the lay flat antenna assembly.
Alternatively, instructions may be provided separately, or even left out entirely, given the simplicity of deployment. The mechanism may even be designed to unfold and lock into place automatically, for example, when shaken firmly or when a spring-loaded catch is released.
Still other embodiments are contemplated. It is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative only of particular embodiments and not limiting. Changes in detail or structure may be made without departing from the basic elements of the subject matter as defined in the following claims.
