Abstract
The present disclosure provides a lens antenna packaging structure, a preparation method and an electronic device. The lens antenna packaging structure includes a rewiring layer stack, a feeder line, a plastic encapsulation layer, an antenna, a lens, a chip and a protruded solder ball. The lens covers the antenna, such that one or a combination of the spherical beam and the cylindrical beam radiated initially from the antenna will be refracted by the lens into a desired shape, to improve the directivity of the beam through the lens, which can enhance the directional gain of electromagnetic waves through the lens, reduce the attenuation and loss of the electromagnetic waves of the antenna, and produce a significant energy saving for 5G base stations and terminals.
