Description

[Detailed Description of the Invention] The present invention relates to the structure of a wireless device with frequencies ranging from the microwave band to the millimeter wave band.

Conventionally, this type of device has been constructed with an aperture antenna, a radio, and a feeder to electrically connect these devices to efficiently radiate radio waves into space or efficiently receive radio waves that arrive after being radiated. It is normal to

Figure 1 shows the constituent countries of conventional microwave radio equipment,
1 is a main reflector made of a paraboloid of revolution, 2 is a primary radiator, 3 is a
4 is a flexible waveguide, 5 is a curved waveguide, 6 is a straight waveguide, and 7 is a radio device.

To operate this device, the main reflector 1 is connected to the primary radiator 2.
After attaching the and sub-reflector 3, fix the main reflector 1 in the direction of the position where it will actually be used, and connect the waveguides 4, 5, and 6.
It was connected to a radio device 7 via a flexible waveguide 4.

Such a configuration has drawbacks such as an increase in feeder loss as the frequency increases and the cost of installing antennas and radio equipment.

In order to solve these drawbacks, the present invention integrates the aperture antenna and the radio case.

The drawings will be explained in detail below.

FIG. 2 is a sectional view of an embodiment of the present invention, in which 8 is a radio, 9 is a radio case whose one side is the main reflecting mirror surface for the antenna, and 10 is an aperture, and a radome that covers the aperture of the antenna. , 11 is the lid of the radio case, 12 is a rubber backing for keeping the radio case watertight, 13 is a primary radiator integrated with the radio 8, 14 is a sub-reflector, and 15 is the radio case 9. , and 16 is a connector for connecting the radio device 8 to the outside.

To operate this device, please check the location where you will actually use this device,
After fixing the direction, necessary power supply and input/output signal cables may be connected via the connection plugs 16.

FIG. 3 is a view of the device shown in FIG. 2 with the lid 11 of the radio case removed and viewed from the direction opposite to the main reflecting mirror surface 15, where 17 is an internal plug, 18, 19°, 20.21 are These are screws for attaching the radio 8 to the radio case 9.

The radio 8 can be easily removed from the radio case 9 by removing the internal plug connection 17 and the screws 1B, 19, 20, and 21 while the device remains fixedly installed. can be replaced or maintained.

At this time, the primary radiator 13 can accurately maintain the relative positional relationship between the main reflecting mirror surface 15 and the sub-reflecting mirror 14 since the secondary radiator mounting portion 25 also serves as a guide for mounting the equipment.

Furthermore, if necessary, the plane of polarization of the radio waves can be easily changed by attaching the radio device 8 with its direction 22 or 23 facing the direction 24 in the figure.

The radio case 9 is molded using a material such as reinforced plastic, and the reflective surface 15 can be produced in large quantities at low cost by using a method such as metal vapor deposition.

Furthermore, when the lid 11 of the radio device case is used in a cold region, an electric heater can be incorporated in the radio device case to maintain the characteristics of the radio device 8.

4, 5, and 6 are side views of installation examples of this device, and FIG. 4 is an example in which this device 33 is installed on a steel tower 28, and 26 is a side view of an example in which this device 33 is installed in a specified direction. The attachment with metal fittings that can be finely adjusted is a metal fitting, and reference numeral 27 is a metal fitting that fixes the attachment fitting 26 and the steel tower 28.

FIG. 5 shows an example in which the device 33 is mounted on a pole 29 via a fitting 26.

FIG. 6 shows an example in which this device 33 is installed on a tripod 32.
Reference numeral 31 indicates a base for mounting the present device 33, and reference numeral 31 indicates a metal fitting with a metal fitting that allows fine adjustment of the present device 33 in a designated direction.

As explained above, the device made according to the configuration of the present invention is very easy to carry, handle, and install, and is suitable for new demands using microwaves and millimeter waves without feeder loss. Compared to wireless devices using conventional methods, this method has advantages such as lower cost, smaller and simpler installation, and easier handling.
