Parabolic antenna with self-structured reflector

Abstract

The present invention relates to a parabolic antenna having a base, mounting pole head unit, rear structure, support pole, low noise converter, and reflector, said reflector being made in a single piece in laminated expanded screen, and having a perfectly parabolic, self-structured shape without any bearing frame, fastened to the rear structure of the parabolic antenna by means of a fastening unit, and having a reinforcement edge facing away from the concavity of the reflector, and rolled or in one or two levels in the peripheral region of the reflector, said reflector having one or more non-perforated or smooth sections, in arbitrary vertical, and/or horizontal orientations, extending over the fastening unit.

Claims

DETAILED DESCRIPTION OF THE INVENTION

(11) FIGS. 1, 2 and 3 show a parabolic antenna (100) with a base (200), a mounting pole (300), head unit (400), rear structure (500), support pole (600) and low noise converter (700), usual in the state of the art and to the skilled in the art, not demanding, therefore, greater details.

(12) A parabolic antenna (100) according to the present invention_with a reflector (800) being made in a single piece, fastened to the rear structure (500) of the parabolic antenna (100) by means of a fastening unit (801), and having a reinforcement edge (802) facing away from the concavity of the reflector (800), and made in a rolled form (FIG. 8) or in one or two levels (FIG. 9) in the peripheral region of the reflector (800).

(13) Thus, a reflector (800) equipped with a reflective surface with a perfect parabolic profile is obtained, and so, with superior performance to the models with conventional state of the art screens described above.

(14) In addition, the parabolic antenna (100) having the reflector (800) according to the present invention does not require structural ribs and bearing frames, thus being lighter and having lower manufacturing cost in comparison to known screen antennas.

(15) For the allocation of a mechanical reinforcement to the parabolic antenna (100) and, thus also the construction of parabolic antennas (100) of larger diameters, the reflector (800) can be equipped with one or more non-perforated or smooth sections (803), in random directions, for example, vertical and/or horizontal, which preferably pass over the fastening unit (801), as can be inferred from FIGS. 4, 5, 6 and 7.

(16) As can be inferred from the description above, the constructive disposition according to the present invention surpasses the state of the art, being an object of practical use, perfectly susceptible of industrial application, comprising a new disposition, involving inventive step and resulting in functional improvement in its use, providing a parabolic antenna (100) with a self-structured reflector (800) made in a single piece in laminated expanded screen, and having a perfectly parabolic shape.
