Description

DETAILED DESCRIPTION OF THE INVENTION [1] (Industrial Application Field) The present invention relates to a portable antenna device used as a terrestrial mobile station for satellite communications, including satellite 1jk transmission, for example.

(Prior Art) In general, antenna devices for satellite communications are required to comply with various antenna standards such as the U.S. FCC standards.
．． A large diameter one such as 5m is required. For this reason, the majority of ijJ 11 type antenna devices using such a reflector were those that were mounted on vehicles in the form of χ·1゛.

However, the portable antenna device described above has a problem in that when it is used in a place where a vehicle cannot move, it cannot be transported and is therefore subject to restrictions on where it can be used.

On the other hand, for conventional portable antenna devices that can be carried by 11 cm by hand, the aperture diameter of the reflector is up to about 1.2 m, which is the most stringent antenna standard according to the U.S. FCC standard. It did not meet the requirements of the law, and was not satisfactory in terms of faith and clarity. Therefore, the U.S. FCC has approved a portable antenna device for such a 1.2m reflector.
Although it is possible to install a reflector with an aperture diameter of 1.8 m or more that complies with the standard, according to this, the mechanical requirements are satisfied by not having a configuration for a large-diameter reflector. This causes the problem that the structure becomes very complicated and the number of packages increases, making handling including folding and unfolding work very troublesome.

For this reason, for portable antenna devices, the U.S. FCC
It is required to ensure a sufficient number of packages that comply with various antenna standards, such as standards, that can be easily transported by hand, and that can be folded and unfolded easily. In this case, the shape and dimensions of each disassembled part must conform to the International Flight Package Standards (including the case) to ensure easy portability: Length + Width + Height ≦ 80 inches
(-2,032 m) Weight (including case): ≦100 lbs (-45,35 m)
9Kg).

(Problems to be Solved by the Invention) As described above, conventional portable antenna devices that comply with various antenna standards such as the U.S. FCC standards are intended for use in vehicles, and are designed to be installed in vehicles where vehicles cannot move. It was difficult to use. In addition, conventional portable antenna devices that can be moved manually do not comply with various antenna standards such as the U.S. FCC standards, and if they were configured to comply with these antenna standards, the structure would be complicated and the package would be Because of the large number of them, handling them was troublesome.

This invention was made in view of the above circumstances, and is designed to be compatible with various antenna standards and international flight package standards, and to reduce the number of packages as much as possible and realize easy handling. The purpose of the present invention is to provide a portable antenna device.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a foldable and unfoldable leg section in which three or more level-adjustable installation sections are provided at predetermined intervals; a mounting part whose orientation can be adjusted freely; a base which is detachably attached to the mounting part and which can be folded and expanded and has an elevation angle adjustment part; and a base which is detachably attached to the base. The flexible reflector plate is attached to a support stand with a part that can be folded and expanded, and the reflector plate of this support stand is attached to a support stand that is detachably supported by the part. A portable antenna device is constituted by a reflecting mirror that can be divided into two parts, and a feeding part that is attached to the feeding part of the support base.

The telescoping mechanisms 52 and 55 are constructed in substantially the same manner as the telescoping mechanism 15 shown in FIG.
The details will be omitted here.

Further, the reflection m 70 is formed of first to sixth divided bodies 71 to 76 divided into, for example, six pieces, and this first to sixth divided bodies 71 to 76 are divided into six pieces.
As shown in FIG. 8, the sixth to sixth divided bodies 71 to 76 are connected via a connecting mechanism 77 having substantially the same structure, thereby forming a mirror surface.

That is, as shown in FIGS. 9 and 10, the first to sixth
