Description

Device for turning direction of microwave and satellite signal receiving antenna

The present invention relates to a structure for adjusting the direction of the antenna for microwave transmission and reception, and in particular, a direction control device for microwave transmission and reception and satellite reception antenna that can be adjusted in all directions of up, down, left, and right directions regardless of the installation position and direction of the antenna. It is to provide.

The present invention applies equally to the antennas for microwave transmission and reception and satellite reception, but the description of the present invention describes a flat antenna for satellite satellite broadcasting reception as an example.

Typical satellite broadcasting systems include television broadcasting and radio broadcasting. In general, television broadcasting uses a parabolic antenna and a radio broadcasting receiving antenna uses a small flat satellite antenna.

Satellite broadcasting broadcasts signals from terrestrial broadcasting stations on the stationary orbit over about 35,000-36,000 km of the equator and relays them back to the ground and receives them from each home using antennas. Since the strength of radio waves on the ground is much weaker than that of VHF and UHF radio waves, not only a high quality antenna is needed, but also the VHF and UHF receiving antennas have an installation position or angle to receive broadcast signals from a broadcasting satellite located at a long distance. It should be much more accurate than.

The antenna for receiving satellite radio broadcasts is composed of a reflector, a patch and a feeder, and a satellite antenna equipped with a low noise amp (LNA), which receives signals emitted from a broadcast satellite, and is connected to a radio set with a tuner. It is possible to receive radio broadcasts.

An antenna for receiving satellite radio broadcasting is a device that directly receives a signal emitted from a satellite. In order to obtain good reception sensitivity, it is necessary to adjust the installation position or the installation angle well. In this case, the adjustment of the installation position means stopping of the equator. It means precisely matching the azimuth and elevation angles between the broadcasting satellites which are regularly located on the track and any receiving area.

1 is a schematic view showing a direction control structure of an antenna for receiving a conventional satellite radio broadcast. As shown in FIG. 1, an antenna unit 1 and a mounting unit 2 are largely formed. Two semi-circular holders 3 are integrally formed at predetermined intervals, and the mounting portion 2 is integrally formed with a circular holder 5 at a length corresponding to the distance between the two semi-circular holders 3. The hinge shaft 4 is inserted into and coupled to the two semicircular holders 3 and the circular holder 5 so as to be rotatable, and an antenna line 6 drawn out from the antenna unit 1 is attached to the mounting portion 2. Four fastening pieces 7 for winding) are formed to protrude, and a screw hole 8 for fixed installation is formed in a four-way corner position.

In the conventional antenna structure for satellite reception configured as described above, the mounting unit 2 is inserted into the rear surface of the satellite reception radio set, or fixedly installed in the external place through the screw hole 8. In this state, the front direction of the antenna unit 1 should be adjusted in the direction of the satellite.

However, since the antenna unit 1 and the mounting unit 2 have a structure in which the hinge shaft 4 is fitted to the holder for coupling, the antenna unit 1 and the mounting unit 2 correspond to the mounting unit 2 around the hinge shaft 4. Rotation of about 90 degrees is possible in the linear direction.

Therefore, when the antenna for receiving the conventional satellite radio broadcast is installed, the angle that can adjust the direction angle is about 90 degrees in the vertical direction (angular angle) and there is a disadvantage that can not adjust the left and right direction.

For this reason, the position and direction for installing the mounting part are very limited, and when it is coupled to the rear of the radio, the installation position and direction are limited, such that the speaker direction of the radio must be directed in the opposite direction to the listener if the direction is not correct. .

Similarly, the microwave transmission and reception antennas need to adjust up and down, left and right and rotation angle directions, but the conventional structure has a disadvantage in that it can not be easily adjusted in the desired direction, and the fixed position and direction must be installed in the transmission and reception direction.

Therefore, an object of the present invention is to provide an antenna direction control apparatus for easily adjusting the direction of the microwave transmission and reception and the satellite antenna in all directions.

The present invention is to provide a direction control device of the antenna to be able to rotate the vertical angle 180 degrees, and to rotate the left and right angles 360 degrees to be adjusted to the full azimuth angle at any position.

In addition, the present invention provides a structure that can be fixed installation irrespective of the installation site or installation target by providing a mounting structure that can be inserted into the rear of the satellite radio, fixed installation on any side and horizontally installed on the rod or chassis rod. It is for.
