Abstract

The invention provides an antenna packaging structure and a packaging method. The packaging method comprises the steps of providing a supporting substrate, forming a rewiring layer, a first antenna layer, a metal feeder column, a packaging layer and a second antenna layer, providing a semiconductor chip, enabling the semiconductor chip to be connected to the surface of the second antenna layer, and forming a box dam dispensing protection layer at least at the top and periphery of the semiconductor chip. A box dam dispensing process is added to wafer-level packaging, the stability of the chip is improved, a bottom filling layer is further formed through a bottom filling process, dual protection is carried out on the chip, the packaging process flow can be effectively reduced, all active components or passive components are integrated in one packaging structure, the packaging size can be effectively reduced, the semiconductor chip, the rewiring layer, the antenna metal and other structures are arranged in a vertical arrangement structure, the conduction path between components can be effectively shortened, the power consumption is low, the integration of the process structure is high, the signal receiving capability can be enhanced by adopting the multi-layer antenna arrangement, and the signal receiving bandwidth can be expanded.
