Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial application field) The present invention relates to a portable antenna device used as a terrestrial mobile station for satellite communication including satellite broadcasting, for example.

(Prior Art) In general, an antenna device for satellite communication is required to conform to various antenna standards such as the U.S. FCC standard.
Large diameters such as 5m are required. For this reason, as a portable antenna device provided with such a reflector, a device intended for in-vehicle use has prevailed.

However, when the portable antenna device is used in a place where the vehicle cannot move, the portable antenna device cannot be transported, so that there is a problem that the use place is restricted.

On the other hand, in the conventional portable antenna device which can be carried by human power, the aperture diameter of the reflecting mirror is up to about 1.2 m, and it does not conform to the U.S. FCC standard, which is said to be the strictest antenna standard, It was not satisfactory in terms of reliability. Therefore, it is conceivable to install a reflector with an aperture diameter of 1.8 m or more that conforms to the U.S. FCC standard for a portable antenna device targeting such a 1.2 m reflector,
According to this, since it does not have a configuration for a large-diameter reflecting mirror, if the mechanical requirements are satisfied, the structure becomes very complicated and the number of packages increases, so that folding and unfolding work is performed. Is very troublesome to handle.

For this reason, in portable antenna devices, the US FCC
It is required to ensure the number of packages that can be easily carried by humans and that can be easily folded and unfolded after conforming to various antenna standards such as the standard. In this case, each of the disassembled parts has a shape and dimensions that can conform to the International Flight Package Standard in order to ensure easy portability. Dimensions (including the case): height + width + height ≤ 80 inches ( = 2.03
2m) Weight (including case): It is required to correspond to ≤100 pounds (= 45.359Kg).

(Problems to be Solved by the Invention) As described above, in the conventional portable antenna device,
Those that correspond to various antenna standards such as the U.S. FCC standard are intended for use in vehicles, and are difficult to use in places where vehicles cannot move. In addition, conventional portable antenna devices that can be carried manually are not compatible with various antenna standards such as the U.S. FCC standard.If they are configured to comply with these antenna standards, the structure becomes complicated, and the number of packages becomes large. And the handling becomes troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been made to be able to conform to various antenna standards and international flight package standards, and to realize simple handling without minimizing the number of packages. It is an object of the present invention to provide a portable antenna device.

A power supply section 90 is attached to the support section 50 at a power supply section mounting section 57, and a connection waveguide 91 connected to a transceiver (not shown) is connected to the power supply section 90 (see FIG. )reference). Then, first to fourth divided bodies 71 to 74 joined by using the coupling mechanism 77 as described above are attached to the reflector mounting member 53 of the reflector mounting member 51. (D)
Then, the fifth and sixth divided bodies 75 and 76 are connected to the first to fourth divided bodies 71 to 74 (see FIG. 9E). Next, an installation part of each leg 12 to 14 of the leg 10
12a to 14a are adjusted and fine adjustment of the level is performed,
The elevation mechanism 40 of the base 30 is operated to finely adjust the elevation angle of the reflecting mirror 70, and the assembly is completed here.

As described above, the portable antenna device has a leg 10 in which the first to third legs 12 to 14 each having the level-adjustable installation portions 12 a to 14 a are provided so as to be foldable and expandable. Lifting mechanism 40 that can be freely attached to and detached from the mounting section 11 that can be used
