Antenna packaging structure
An antenna packaging structure includes a packaging container and an antenna contained in the packaging container. The antenna includes a flexible substrate, an antenna element disposed on the flexible substrate, a feeder structure connected to the antenna element, and a coaxial cable connected to the feeder structure. The flexible substrate of the antenna is rolled into a cylindrical structure, with the antenna element rolled together with the flexible substrate and retained electrical properties after unrolled, the feeder structure is disposed inside or to a side of the cylinder structure, and the coaxial cable is disposed inside the cylinder structure or between the cylinder structure and the packaging container. The present disclosure can effectively ensure safety and stability of the antenna during transportation and storage, reduce risk of damage due to external forces or environmental factors, provide compressed space occupied, and correspondingly improve efficiency of transportation and storage.
