Indeed, according to the invention, even the careful observer should not be able to notice that the antenna enclosure is not what it appears to be, e.g., the top floor of a building, a penthouse, or standard rooftop screening used commonly to house HVAC systems.
  • building element is meant to have a generic meaning, including but not limited to either the block-like configuration of Figures 1A-C or the panel-like configuration of Figures 2A-C.
  • the term should be thought of as comprising any building element designed and constructed as falling within the scope of the invention defined herein.
  • Figure 1 A is an elevation view of a first preferred embodiment of building element 10 for constructing antenna enclosures according to the invention.
  • Block-like building element 10 will typically be rectangular and have planar surfaces.
  • the shape of building element 10 depends upon the final shape of the antenna enclosure to be constructed.
  • building elements 10 may be arcuate (Figure 1C) to allow for the construction of circular or round antenna enclosures, such as those having the appearances of grain silos or water towers, as described below.
  • the first embodiment of building element 10 typically comprises three components, namely: first and second outer skin layers 12 and inner core 15.
  • Inner core 15 provides the primary structural rigidity and strength to building element 10 and will typically be made from a closed cell foam such as polystyrene, although other lightweight materials may also be used so long as the material selected is structurally sound and substantially transparent to the electromagnetic waves to be received or discharged by the antenna to be enclosed.
  • First and second outer skin layers 12 are typically made from conventional ABS (acrylonitrile butadiene styrene) made by a variety of manufacturers. One well known source of ABS is Spartech Plastics. Alternative materials that can be used for outer skin layers 12 include Duraform Architectural Telecommunications Panels made by Vacuform Industries, Inc.
  • First and second outer skin layers 12 are more for protecting the closed cell foam from the outdoor elements, and treatment with decorative material, as will be described below. Structural strength is not a primary concern of skin layers 12. Therefore, the primary concerns in selecting the material for outer skin layers 12 are: substantial transparency to electromagnetic waves and amenability for treatment such as painting, thermo-forming, or epoxy ing to make building elements 10 look like either the surrounding architecture or whatever the antenna enclosure is to have the appearance of. ABS has been found to excel in both roles and is therefore highly preferred.
  • outer skin layer 12 can be treated to have the appearance of bricks and mortar or whatever the building is constructed of so that the antenna enclosure looks like the top floor of the building. Even air conditioning ducts, vents, and louvres may be simulated so that the antenna enclosure can be made to look like a structure enclosing roof-top utility equipment.
  • the outer skin layer 12 can be treated to have the appearance of the materials typically used to make grain silos. It is also possible to enclose cellular antennas on water towers. The variations are endless.
  • building elements 10 are treated to look like either the surrounding architecture or whatever the enclosure is to have the appearance of.
  • This treatment can be done in a variety of ways.
  • the simplest method of generating a desired appearance involves merely painting outer skin layer 12 so that it has the desired appearance.
  • brick and beige colored paints can be used to simulate brick and mortar and silver paint can be used to simulate the shiny metal sometimes used to construct a grain silo.
  • care must be taken that the material out of which outer skin layer 12 is made does not encourage the paint to peel off.
  • Another method of generating the desired appearance comprises thermo-forming outer skin layer 12 with the desired appearance.
  • a hot grid may be placed onto outer skin layer 12 so as to form indented rectangular outlines.
  • the outlines themselves can then be painted the color of mortar while the areas that they bound can be painted the color of bricks. This will provide for a more three- dimensional appearance of the enclosure surface, thereby making it look even more like what it is supposed to.
  • a combination of thermo-forming and painting could be used to make outer skin layers 12 have the appearance of air conditioning ducts, vents, and even louvres.
  • epoxy ing may be used to generate the desired appearance. This involves building up areas of outer skin layer 12 with epoxy to generate a particular relief consistent with the desired appearance. For example, bricks or stucco can be simulated. The dried epoxy is then painted the desired colors.
  • the primary concern is always that the material be transparent to the electromagnetic waves to be received or discharged by the antenna to be enclosed, i.e., allows them to pass through the material with only minimal interference and signal degradation.
  • Building elements 10 according to the first embodiment of the invention are constructed such that they can interlock with each other when constructing an antenna enclosure. However, this ability to interlock is not critical to the success of the invention.
  • One way of achieving the interlock of building elements 10 is by offsetting first and second outer skin layers 12 from inner core 15. As shown in Figures IB, 1C, this offsetting results in a front portion 21 of inner core 15 extending past the front edges 19 of first and second outer skin layers 12 and a rear portion 22 of inner core 15 extending inward from the rear edges 17 of first and second outer skin layers 12, thereby forming a V shaped area 23. As shown in Figure 3 A, two building elements 10 are interlocked by placing front portion 21 of the first building element 10 in the 'u' shaped area 23 of the second building element 10. A slight friction fit between rear edges 17 of first and second outer skin layers 12 and front portion 21 of inner core 15 is useful to keep the building elements 10 in contact with one another.
  • gap G of approximately 1/8" is provided between rear edges 17 of one building element 10 and front edges 19 of second building element 10 to account for thermal expansion of the ABS or other material used to make skin layers 12.
  • the inner cores 15 of both building elements 10 may be abutted against each other because their material of construction is typically not subject to much thermal variation.
  • FIG. 3B An alternative method by which two of the first embodiment of the building elements 10 according to the invention can be interlocked is shown in Figure 3B.
  • front portion 21 and rear portion 22 of core 15, itself are formed into groove 25 and tongue 27, respectively.
  • tongue 27 of one building element 10 is placed into groove 25 of the other building element 10.
  • first and second outer skin layers only need span the length of core 15 and are constructed to provide for the gap G in the manner as described above with respect to Figure 3A.
  • FIG. 3D shows two building elements 10 joined together to form a corner of an antenna enclosure.
  • Inner cores 15 meet at a right angle to form the corner. Any appropriate adhesive means can be used to secure the two cores together.
  • Outer skin layer 12o is formed to wrap around the corner providing additional stability.
  • inner skin layer 12i can be used to wrap around the inside of the corner for maximum stability.
  • Figure 3E shows a second embodiment of the corner where each inner core 15 has its own inner skin layer 12i.
  • FIG. 4 A shows an antenna enclosure 50 made substantially from interlocking building elements 10. Angle irons 55 and cross beam 60 are the only additional structure used to support the enclosure. Cross beam 60 may also be used as a support for hanging the antenna. While this antenna enclosure will not have the same structural integrity as enclosures with more substantive infrastructures, it has the advantage that there is less structure to interfere with the electromagnetic waves. The antenna enjoys full 360° transmission and reception capability even through the corners of the enclosure.
  • Electromagnetic waves must be able to pass through building elements 10 without much deterioration in signal.
  • the above materials i.e., closed cell foam and ABS
  • the dimensions of building element 10 are not that important. Therefore, while it is preferable to have the foam core and each of the outer ABS skin layers about 2" and 1/8" thick, respectively (Figure IB), the thickness used depends primarily on two factors: 1) how much additional structure is employed to support the antenna enclosure, and 2) the wavelength of the signal to be transmitted or received.
  • FIG. 2A, 2B, and 2C A second embodiment of a building element according to the invention is shown in Figures 2A, 2B, and 2C.
  • Figures 2A and 2B the rectangular, planar version of building element 10' is shown.
  • Figure 2C the arcuate version of building element 10' is shown.
  • Both versions of building element 10' are formed by taking outer skin layer 12', made from a material substantially transparent to the electromagnetic waves to be received or discharged by the antenna to be enclosed, preferably ABS, and integrally attaching structural support members 38 along its width at various intervals. Due to its relatively thinner configuration, the second embodiment of building element 10' is sometimes referred to as a "panel" (cf. the first embodiment of building element 10 sometimes referred to as a "block").
  • Support members 38 are provided to supply the structural integrity needed to resist wind shears due to the absence of core 15. While it is preferred that structural members 38, which may also be known as hat channels or channel members due to their inverted hat-channel-like cross-section, be integral with skin 12', it is also possible for structural members 38 to be separate members and implemented as will be described below. Structural members 38 are associated with the side of skin 12' opposite the side to be treated to look like the surrounding architecture or locale. Finally, as shown in Figure 3C, end brackets 40 having fastener holes therethrough are provided to join together two building elements 10' end-to-end by use of fasteners F.
  • FIG. 4 illustrates an example of an antenna enclosure 50 made from building elements 10 and a cantilever support structure.
  • This enclosure can as easily have been constructed using building elements 10'. Indeed, in discussing enclosure 50, when differences come up that would result from the use of building elements 10' rather than 10, the nature of the difference will be discussed. Otherwise, the steps in building enclosure 50 out of building elements 10' are the same as when building it out of elements 10.
  • Exemplary antenna enclosure 50 is constructed generally as follows, although it is possible to vary the order of the steps somewhat:
  • Base mounts 35 are fastened to the surface on which antenna enclosure 50 is to be built.
  • This surface may comprise, for example, the roof of a building or a concrete slab at ground level;
  • FIG. 1 Main vertical support i-beams 37 are attached to base mounts 35.
  • Figures 5 and 6 show side and corner vertical supports 37 and their attachment to base mounts 35;
  • Cantilever supports 39 are attached to vertical supports 37 (see Figures 4, 5, and 6) at strategic locations based on the size of building elements 10 and the overall shape of antenna enclosure 50.
  • Lower horizontal tracks 44 are attached to cantilever supports 39 by use of fasteners F (see Figures 4 and 11), so as to construct a track conforming to the desired antenna enclosure shape, which in this example is rectangular, but may be triangular or any other shape;
  • Brace beams 41 are attached to opposing main vertical supports 37 to provide horizontal stability for the structure. In alternative embodiments, brace beams 41 could be attached to a building foundation or any other stabilizing source; 6) Upper horizontal tracks 43 are then secured to cantilever supports 39 by fasteners F. Building elements 10 are then stood upright or lengthwise, depending upon the desired height for the antenna enclosure, within the rectangular tracks defined by the upper half of lower horizontal track 44u (see Figure 11) and the lower half of upper horizontal track 43i. If building elements 10' are used, structural members 38 should be of proper width to fit into the horizontal tracks or L-channel spacers (not shown) could be used to take up any extra space. Lines 40 (see Figure 4) represent seams between adjacent building elements 10.
  • FIGS 10 and 11 illustrate the reception of building element 10 between the horizontal tracks.
  • Horizontal tracks 43 and 44 are preferably I or H-shaped to allow for reception of a building element 10 in one channel and the use of fasteners F in the other channel as shown in Figures 10 and 11.
  • main vertical supports 37, upper and lower horizontal tracks 43 and 44, cantilever supports 39, and brace beams 41 may be made from a material substantially transparent to electromagnetic waves.
  • that material will be fiberglass due to its light weight and transparency to electromagnetic waves.
  • the choice of material used for the structural members will depend primarily on the type of antenna to be enclosed and the size of transparent window required. For example, if the antenna is aimed out one side of the enclosure, it is not necessary to use an expensive material such as fiberglass or ABS for the entire support structure.
  • Base mounts 35 may be made from fiberglass or even steel since there is no chance that incoming or outgoing electromagnetic waves will pass through base mounts 35.
  • Figure 12 illustrates an additional example of an antenna enclosure 50 made from building elements 10 according to the invention, in this particular case using the second embodiment of building elements 10'.
  • This enclosure can as easily have been constructed using building elements 10. Indeed, in discussing enclosure 50, when differences come up that would result from the use of building elements 10 rather than 10' , the nature of the difference will be discussed. Otherwise, the steps in building enclosure 50 out of building elements 10 are the same as when building it out of elements 10'.
  • Exemplary antenna enclosure 50 is constructed generally as follows, although it is possible to vary the order of the steps somewhat:
  • Base plates 135 are fastened to the surface on which antenna enclosure 50 is to be built.
  • This surface may comprise, for example, the roof of a building or a concrete slab at ground level;
  • Main vertical supports 137 are attached to base plates 135;
  • Lower horizontal tracks 139 are attached to main vertical supports 137 by use of fasteners F (see Figure 16), so as to construct a track conforming to the desired antenna enclosure shape, which while in this example is rectangular, may be triangular or
  • Angular beams 141 are attached to main vertical supports 137 and to the surface on which enclosure 50 is to be built, such as by use of baseplates similar to baseplates 135;
  • Top caps 143 are positioned over the tops of secondary vertical supports 138 and building elements 10' ( Figures 12, 13) and by use of fasteners F fastened to main vertical supports 137 ( Figures 13-15) to cause secondary vertical supports 38 and building elements 10' not to fall outward with respect to enclosure 50 ( Figures 14 and 15) and provide enclosure 50 with the ability to resist wind shears. While when the first embodiment of building element 10 is used to build antenna enclosure 50, secondary supports 138 are not needed, top caps 143 are always needed to keep the building elements from falling inward and to hold enclosure 50 together. Top caps 143 are typically horizontal. Alternatively, as shown in Figure 16, a second set of tracks 139 could be used to make a taller enclosure 50. However, even then, top caps 143 will be needed at some point; and
