Definitions
- This utility model belongs to the field of telecommunications equipment industry, notably satellite communication antennas.
- This utility model relates to a constructive arrangement introduced in a telecommunication antenna, especially a satellite communication antenna of the type used, for example, for receiving satellite pay-TV or DTH (Direct-to-Satellite) signals.
- Home-to-Home commonly known as a satellite dish.
- the satellite dish according to the present utility model features a perfectly parabolic self-structuring reflector assembly made of lightweight, rigid, wind-permeable, expanded laminated mesh with optimized material utilization. metal and consequent reduction of manufacturing cost.
- This construction is generally made by segmenting the reflective surface, as shown for example by US 4,578,682, US 2,997,712, US 3,234,550 and US 4,647,943, in various segments supported by ribs, sleepers, spars, fins. Finally, a series of components that increase the number of items of an antenna, the complexity of assembly and, almost always, its final mass.
- segmentation of the reflective surface and the lack of structural rigidity of the metal screens make it impossible to achieve a parabolic shape as perfect as that of solid one-piece patterned rigid screens, resulting in semi-parabolic antennas or umbrella format.
- the purpose of the present utility model is therefore to provide a self-structuring reflector satellite dish in accordance with the features of claim number 1 of the attached claim table. Variation of shape or detail related to component elements of the model that do not alter the technical-functional and bodily unit of the object of claim 1 are defined in the claim dependent on the attached claim table.
- Figure 1 presents an anterolateral perspective view of a self-structuring reflector satellite dish according to the utility mode
- Figure 2 presents a posterolateral perspective view of a parabolic antenna with self-structuring reflector according to the utility mode
- Figure 3 shows a side view of a self-structuring reflector satellite dish according to the utility model
- Figure 4 presents an anterolateral perspective view of a shape variation of the self-structuring reflector satellite dish according to the utility model.
- Figure 5 presents an anterolateral perspective view of a shape variation of the self-structuring reflector satellite dish according to the utility model
- Figure 6 presents an anterolateral perspective view of a shape variation of the self-structuring reflector satellite dish according to the utility model
- Figure 7 presents an anterolateral perspective view of a shape variation of the self-structuring reflector satellite dish according to utility mode
- Figure 8 shows detail "A" of figure 6f in the coiled condition
- Figures 1, 2 and 3 show a satellite dish (100) provided with base (200), pedestal (300), helmet (400), rear frame (500), staff (600) and low noise converter ( 700), usual in the state of the art and known to those skilled in the art and technicians in the subject, thus not requiring further detail.
- a satellite dish (100) according to the present utility model has a one-piece reflector (800) fixed to the rear frame (500) of the satellite dish (100) via a clamping unit (801 ) and said reflector (800) having a reinforcing edge (802) facing in the opposite direction to the concavity of the reflector (800) and carried out in a coiled manner (figure 8) or on one or two levels (figure 9) in peripheral region of the reflector (800).
- the satellite dish 100 provided with the reflector 800 according to the present utility model dispenses with structural ribs and supporting frames and is therefore lighter and less expensive to manufacture than known screen antennas. .
- the reflector (800) may be provided with one or more unperforated or smooth sections ( 803), in random orientations, for example; and / or horizontal, preferably passing over the clamping unit 801, as can be inferred from Figures 4, 5, 6 and 7.
- the constructive arrangement according to the present utility model overcomes the solutions of the state of the art, being an object of practical use, perfectly susceptible of industrial application, that presents new disposition, involving inventive act and resulting in functional improvement in its use, providing a satellite dish (100) equipped with self-structured reflector (800) made in one piece in expanded parabolic format laminated expanded canvas.
