US Patent 11165143 Antenna module and electronic system including the same

An antenna module includes an antenna substrate, a fan-out package and first electrical connection structures. The antenna substrate includes a pattern layer including antenna and ground patterns, and a feeding layer under the pattern layer including a feeding network that supplies power to the antenna patterns. The fan-out package is under the antenna substrate and includes a semiconductor chip driving the antenna substrate, an encapsulant encapsulating some of the semiconductor chip, a first redistribution layer on the semiconductor chip electrically connecting the semiconductor chip with the antenna substrate, and a second redistribution layer under the semiconductor chip electrically connecting the semiconductor chip with external devices. The first electrical connection structures are between and electrically connect the antenna substrate and the fan-out package. A logic layer including logic patterns electrically connecting the pattern layer with the feeding layer in the antenna substrate in the first redistribution layer in the fan-out package.
