Description

Technology Field

[0001] The present invention relates to a satellite reflector antenna, and more specifically, to a foldable reflector antenna in which a plurality of reflectors are connected through a hinge and folded. Background Technology

[0002] Satellite antennas are commonly used in satellite communication, high-capacity wireless communication, and the like. The satellite antenna utilizes the principle of a reflecting telescope to focus a received signal onto at least one focal point. Generally, an antenna feed can be installed at the focal point of the satellite antenna.

[0003] Since satellite antennas must always have an antenna feed positioned toward a satellite at a constant location, they generally have a pedestal structure capable of rotating around two or three axes. To enable this rotational movement, a power transmission unit using multiple belts and pulleys is used in satellite antennas.

[0004] Furthermore, various types of mobile satellite receivers are currently being researched and developed to ensure seamless communication between satellite antennas mounted on the mobile systems of vehicles, such as cars and ships, and the satellites themselves. A mobile satellite receiver is a device designed to maintain good reception conditions by ensuring that the antenna accurately points toward the satellite, in the face of receiver movement, changes in direction, and the influence of various disturbances.

[0005] However, when transportation was required, conventional reflector antennas were inconvenient to transport, and even if the parts were disassembled for transport, installation was inconvenient. Prior art literature

[0015] In relation to the description of the drawings, similar reference numerals may be used for similar components.

[0016] A singular expression may include a plural expression unless the context clearly indicates otherwise.

[0017] In this document, expressions such as "A or B" or "at least one of A and / or B" may include all possible combinations of the items listed together.

[0018] Where it is stated that a certain (e.g., first) component is "(functionally or telecommunicationally) connected" or "connected" to another (e.g., second) component, the certain component may be directly connected to the other component or connected through another component (e.g., third component).

[0019] As used in this specification, singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as “composed” or “comprising” should not be interpreted as necessarily including all of the various components or steps described in the specification, and should be interpreted as meaning that some of the components or steps may not be included, or that additional components or steps may be included.

[0020] FIGS. 1 and 2 are perspective views of a foldable reflector antenna in use related to an embodiment of the present invention.

[0021] As illustrated, the foldable antenna (100) includes an antenna feed (200) and a reflector (300).

[0022] The antenna feed (200) is positioned through the central part of the reflector (300) to receive the satellite signal reflected from the reflector (300) and focus the satellite signal.

[0023] The reflector (300) may include a plurality of plates. The plurality of plates may have polygonal shapes. The plurality of plates may all have the same polygonal shape, or they may be composed of a combination of polygons that have different shapes but have the same side length. For example, the plurality of plates may all have a hexagonal shape, or some plates may have a pentagonal shape and other plates may have a triangular shape with a side length equal to that of the pentagon.

[0024] Below, we will describe an example in which all of the multiple plates have a hexagonal shape.

[0025] FIG. 3 is a front view of a foldable reflector antenna in use according to an embodiment of the present invention, and FIG. 4 is a drawing for explaining the principle of folding or unfolding a plurality of plates constituting the reflector of a foldable reflector antenna according to an embodiment of the present invention.

[0026] As described, the reflector (300) may include a plurality of plates having a hexagonal shape. The plurality of plates forming the reflector (300) may include one central plate (310) located in the center, six fixed plates (320) connected to each corner of the central plate (310), and twelve hinge plates (330) connected to the fixed plates (320) through a hinge (340).

[0027] The antenna feed (200) can be positioned through the central plate (310). The central plate (310) and the fixed plate (320) can be connected to each other in a fixed manner. The central plate (310) and the fixed plate (320) can be connected at a predetermined angle (an angle that converges inward relative to the front) that is less than 180 degrees.

[0028] The hinge plate (330) is connected to one corner of the fixed plate (320) via a hinge so that it overlaps with the upper or lower surface of the fixed plate (320) or can be unfolded without overlapping with the upper or lower surface of the fixed plate (320). When transporting the reflector antenna (100), the hinge plate (330) can be positioned to overlap with the upper or lower surface of the fixed plate (320). Additionally, when installing the reflector antenna (100), the hinge plate (330) can be positioned to unfold without overlapping with the upper or lower surface of the fixed plate (320). In this case, the hinge plate (330) and the fixed plate (320) can be connected at a predetermined angle (an angle that converges inward relative to the front) that is less than 180 degrees.

[0029] The hinge plate (330) may include an upper hinge plate (331) and a lower hinge plate (332).

[0030] The upper hinge plate (331) can be overlapped with the upper surface of the fixed plate (320), and the lower hinge plate (332) can be overlapped with the lower surface of the fixed plate (320). The hinge (340) connecting the upper hinge plate (331) and the fixed plate (320) is located on the upper side of the fixed plate (320), and the hinge (340) connecting the lower hinge plate (332) and the fixed plate (320) can be located on the lower side of the fixed plate (320).

[0031] When the foldable antenna (100) is transported in a state as shown in FIGS. 5 to 6, the convenience of transport can be increased, and the ease of installation can also be increased by easily unfolding the upper hinge plate (331) and the lower hinge plate (332) during installation.

[0032] As described above, the foldable reflector antenna according to one embodiment of the present invention can be conveniently transported by folding the reflector without special disassembly or assembly, and can be easily installed by unfolding the reflector when installing.

[0033] The foldable reflector antenna described above is not limited to the configuration and method of the embodiments described above; rather, all or part of each embodiment may be selectively combined to allow for various modifications to be made.
