| titleOfInvention | 5G base station millimeter wave antenna housing and manufacturing method thereof |
| abstract | The invention discloses a 5G base station millimeter wave antenna housing and a manufacturing method thereof, wherein the manufacturing method comprises the following steps: drawing a 3D model of the 5G base station millimeter wave antenna housing, and drawing a 3D model of a 5G base station millimeter wave antenna housing mould according to the 3D model; calculating the compression creep percentage of the foam sandwich material according to the density of the foam sandwich material and the internal pressure provided under the compression creep, and determining the thickness of the foam sandwich material according to the compression creep percentage and the final thickness of the foam sandwich layer after forming; milling the foam sandwich material; forming a first skin, a flange solid area and a second skin; sequentially laying a first skin, a foam sandwich material, a flange solid area and a second skin, vacuumizing and pre-compacting; and (3) after the upper die and the lower die are closed, placing the upper die and the lower die into a press for mould pressing and co-curing for forming, and determining forming pressure according to the internal pressure provided under the compression creep of the selected foam sandwich material. The radome has high wave transmittance, good phase consistency and good wave transmittance uniformity. |
