An antenna chip packaging structure and a method for preparing the antenna chip packaging structure are disclosed. The method includes forming multiple antenna structures: on a first support substrate with a redistribution layer on the first support substrate; forming each of the multiple antenna structures includes sequentially forming a first antenna layer, a first connection structure, and a first packaging layer on the redistribution layer; sequentially forming a second antenna layer, a second connection structure, and a second packaging layer above the first packaging layer; forming a third antenna layer above the second packaging layer; repeating the antenna structure forming process, before bonding a second support substrate above the last antenna structure on the last packaging layer; removing the first support substrate, and forming a UBM layer below the redistribution layer; and forming a solder ball on the UBM layer and connecting a chip to the UBM layer.
