良に関するものである。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is used for microwave communication between a geostationary satellite and the ground. The present invention relates to an improvement in an antenna device that includes a direction adjustment section that adjusts the direction of a main beam of radio waves.
静止衛星と地上間のマイクロ波通信に使用されるアンテ

ナの主ビームのビーム幅杜約1度であり、0.2度程度
の精度で方向調整を行なう必要がある。In an antenna device used for microwave communication between a geostationary satellite and the ground, it is necessary to direct the main beam of the antenna device toward the geostationary satellite. For example, the beam width of the main beam of an antenna with an aperture diameter of 1 m used in the 12 GHz band is about 1 degree, and the direction must be adjusted with an accuracy of about 0.2 degrees.
また、地上から見た静止衛星の方向は、静止術(2) 星の位置および地上の緯度、経度によって定まり。Also, the direction of a geostationary satellite as seen from the ground is determined by geostationary technique (2). Determined by the position of the stars and the latitude and longitude of the ground.
上記方向は地上の各部市によってそれぞれ異なる。The above directions differ depending on the area on the ground.
例えば静止衛星の位置を東経110度の静止軌道上とす
ると、方位角および仰角は表1に示す値となる。For example, if a geostationary satellite is located on a geostationary orbit at 110 degrees east longitude, the azimuth and elevation angles will be the values shown in Table 1.

It was displayed. The direction was then adjusted using this angle as a reference. This is because such an antenna device requires synchro transmitters (5a) (5b) and an angle display section (6).
高価になるという問題点があった。また、このようなア
ンテナ装置の設置場所が異なる場合1例えば東京あるい
は札幌という場合にはそれぞれ静止衛星の方向が異なる
ので、それらの方向を示した資料が必要になるという問
題点があった。The problem was that it was expensive. Furthermore, when such antenna devices are installed in different locations (for example, in Tokyo or Sapporo), the directions of the geostationary satellites are different, so there is a problem in that materials showing these directions are required.

テナ装置のビーム幅が狭い場合には受信レベルの強い範
囲が狭いので方向調整が難しいという欠点があった。In addition, as shown in Figure 2, in the case of an inexpensive antenna device that does not use a synchro transmitter or an angle display, it is necessary to adjust the direction by referring to a reception level monitor device (7) such as a receiver. . Therefore, when the beam width of the antenna device is narrow, the range where the reception level is strong is narrow, making it difficult to adjust the direction.
この発明はこのような欠点を除去するために。 This invention aims to eliminate such drawbacks.
アンテナ装置に水平度を測る水準器を組み込むことによ

An elevation angle adjustment part (4) and a level (8) are provided on the back side of the reflector (2), and the angle of the reflector (2), that is, the reflection by the reflector (2), is adjusted using the level (8) as a reference. It is possible to adjust the direction of the radio waves toward the geostationary satellite. That is, as shown in Figure 4, the level (8)

A scale is provided on the inside or outside of the joint (7) between the structure (9) and the structure (9). Therefore, by reading the scale when the level (8) is set horizontally, the elevation angle of the main beam can be known, and the direction of the main beam can be adjusted while observing the inclination of the level.

By writing the name of each city in the position field, you can easily direct the main beam of the antenna device toward the geostationary satellite.
