Problems solved by technology
[0003] In order to eliminate external interference electromagnetic signals, the antenna of 5G communication products needs to carry out electromagnetic shielding treatment on the circuit board transmitted by the antenna to prevent other components from interfering with the signal transmission of the circuit board. At the same time, it also prevents the antenna circuit board from interfering with other components, but the existing shielding structure has poor effect on millimeter waves, and it is urgent to solve the electromagnetic shielding problem of the antenna structure
Since the wave band of 5G communication products is millimeter wave, the existing electromagnetic wave shielding film has poor shielding effect, and the existing full-covering method wastes materials, and the structural stability is poor, and it is prone to breakage at corners and steps

Description
technical field [0001] The invention relates to the technical field of shielding films, in particular to an omnidirectional shielding antenna structure and antenna. Background technique [0002] With the development of communication technology, 5G communication technology has gradually matured. In 5G communication, in order to improve the transmission speed, 5G communication uses high-frequency electromagnetic waves for signal transmission, and the transmission speed has been significantly improved. The high-frequency band of commercial 5G will use the 28GHz frequency band and the 60GHz frequency band. The wavelengths of the 28GHz frequency band and the 60GHz frequency band are millimeter-level, that is, millimeter waves. [0003] In order to eliminate external interference electromagnetic signals, the antenna of 5G communication products needs to perform electromagnetic shielding on the circuit board transmitted by the antenna to prevent other components from interfering wi...
