Abstract

The invention provides an antenna packaging structure and a packaging method. The packaging method comprises the steps of providing a supporting substrate, and forming a rewiring layer, a first antenna layer, a first metal feeder column, a first packaging layer, a second antenna layer, a second metal feeder column, a second packaging layer, a third antenna layer, a semiconductor chip, a metal bump and a third packaging layer. The semiconductor chip is protected based on the third packaging layer, the chip and the metal bump are packaged at the same time, the stability of the packaging structure can be effectively improved, the holes are formed in the packaging layer firstly, then the metal bump is formed, the process is simplified, preparation of the metal bump is facilitated, and the multilayer antenna structure is formed through the multiple metal feeder columns and the multiple packaging layers. The packaging size is reduced, the signal receiving capability is enhanced, the signal receiving bandwidth is expanded, the bottom filling layer is formed, the packaging stability is improved, the box dam dispensing process is added, the stability of the chip is improved, dual protection is carried out on the chip, the packaging process flow can be effectively reduced, and the process period is prolonged.
