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, a multi-layer antenna structure is formed through the multi-layer metal feeder columns and the multi-layer packaging layer, the packaging size can be small, the signal receiving capacity can be enhanced, the signal receiving bandwidth can be expanded, a bottom filling layer is formed, and thepackaging structure stability is improved; the semiconductor chip, the rewiring layer, the antenna metal and other structures are arranged in a vertical arrangement structure, so that the conduction path between components can be effectively shortened, the electrical property and the antenna performance are better, the power consumption is lower, and the process structure integration is high.
