Description

Method for manufacturing radiator structure of 5G repeater {A Method for Manufacturing Radiator Structure of 5G Repeater}

The present invention relates to a method of manufacturing a radiator structure, and more particularly, it is possible to increase manufacturing efficiency by shortening the working time required for manufacturing the radiator structure, and to reduce the defect rate of the product by simple and accurate processing. The present invention relates to a method for manufacturing a radiator structure of a 5G repeater that can reduce the sizing and further improve the performance of a base station or repeater antenna.

An antenna of a base station or a repeater for mobile communication generally includes a plurality of radiators, and transmits and receives signals using beams output from these radiators.

Recently, the era of 4G mobile communication standard LTE has passed, and the 5G era, which is the 5G mobile communication standard, has arrived.There is a demand for radiator structures with excellent performance that can be used in various equipments including antennas of base stations or repeaters required in the 5G era. Since the situation is increasing, there is a need for simple and efficient manufacturing in order to supply the radiator structure more quickly.

On the other hand, the radiator structure requires a number of fixing holes for fixing to a specific position of the antenna or connecting a plurality of radiators to each other, and these fixing holes include a pem nut for fastening bolts, etc. A press-fitting nut including a stand-off nut, a pop nut, etc. is press-fitted so that it can be simply and accurately placed or fixed at a desired position.

However, in the conventional method of manufacturing a radiator structure, generally, holes for fixing the radiator structure and mounting parts are formed by NCT (Numerical Control Turret punch press) processing method, so that a plurality of holes are formed. In this case, the working time becomes longer, and there is a problem that the plate may be warped during the process of individually forming the holes.

In addition, since the laser processing step of cutting the outer shell using a laser to form the outer shape of the radiator structure after forming the hole was performed as a separate operation, the overall manufacturing process takes a long time, so the operation is not efficient and accurate. Since a hole may be formed at a location that is not, there is a problem in that the radiator structure is deviated, which adversely affects the performance of the antenna or repeater.

Furthermore, in the conventional manufacturing method, since the press-fitting nut is individually press-fitted to a desired position when the press-fitting nut is press-fitted, there is a problem that the press-fitting of the press-fitting nut is liable to occur and thus the completeness of the product is degraded.

If the hole diameters are different from each other, it takes an additional time to set up the equipment, so the work time is further lengthened.

In addition, since a force is partially applied to the raw material plate in the process of individually forming the hole, the raw material plate may be partially bent, so there is a problem that adversely affects the performance of the antenna or repeater.

In addition, since the laser processing step of cutting the outer shell using a laser to form the outer shape of the radiator structure after forming the hole was performed as a separate operation, the overall manufacturing process takes a long time, so the operation is not efficient. As previously discussed, since holes may be formed at locations that are not, there is a problem that has a bad influence on the performance of the antenna or repeater due to the deviation of the radiator structure.
